Introduction: April Fools Pen

Picture of April Fools Pen

This is a avery simple April Fools Joke. It can be played on anyone but the more intensely focused a person is the better. I used it on my manager and several others and I got everyone. Some play acting is required.

You need:
2 BIC Pens (you know the 100 pack ones you can get at the drug store)
a victim or two or three or four

Step 1: Open the Pen

Take the cap off the pen and gently pull on the writing part of the pen it should come apart fairly easily.
At this point you have:
a pen filler
a pen cap
a hollow pen with one plug in an end of it

Step 2: The Second Pen...

All you need from the second pen is the plug in the end of the pen. I gently pried my finger nail under the edge and it came right out.

Step 3: Assembly

Now take the plug from the second pen and press it into the empty end of the hollow tube from the first pen.

You can keep the actual pens for use as refills in other pens or deconstruct these after the joke and use them normally.

Step 4: All Finished... Now Go Find Your Victim

Place the either of the pen caps back on the double plugged hollow tube and it looks like an ordinary pen.

Finding your victim:
The best victim is an extremely focused individual.

ALSO try to get into theior office and hide all other pens this makes things really easy

Find several things you need to have them sign or mark up or something but state that it is very confusing and the they need to look at it carefully.

Hand them the documents and the 'pen' at the same time.

Generally the person will focus on the content and not even think about the pen.

When they get done 'examining the confusing document or sometimes even while they are examining it they will glance at the pen notice it is capped and uncap it moving the cap to the other end in preparation for signing.

They then go to sign and the see the pen is still capped so they uncap it again and move the cap to the other side and wallaaaa it is still capped.

Depending on how intensely focused on the confusing document they are, they may actually uncap the same hollow tube several times before they even catch on.

Note several of these pens can be placed in offices and the fun can last all day long.

You can even get the same person multiple times in this way.

It works best if another person hands the boss the pen.

I have done this for years, almost as long as they have been making the Biro. The brilliant part was to make an Instructable about it, which you did, and brilliantly!

grundisimo (author)2009-04-18

i will try this on my dad as soon as possible. THIS IS AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Saturn V (author)grundisimo2010-04-05

agreed. I'm gonna buy the pack of 100, do this to every single one, and give the 50 pens to my teachers.  THAT WILL BE HILARIOUS!!!!!!!!!!!!!!!!

reubyjay (author)2010-04-01

 I am so doing this on my mom next time she needs a pen, and congrats on winning

carpfluff (author)2010-04-01

This one is great! My cousin bought the 100 pack and all day we made these out of them all. Great prank =)

porcupinemamma (author)2010-03-29

Fun! ;0)

They will probably take the cap off and notice that the pen is double capped.

jjanes (author)woody5582010-03-17

You would be surprised I think I mentioned this somewhere that it works REALLY well on TYPE A personalities they are focused on the most important things as are most of us but TYPE A's especially and most people don't notice.

I did this to a manager of mine a long time ago and she actually turned it over and over 3 times she just absent-mindedly thought she had missed the fact that the pen was already open and put the cap on instead of taking it off so she did it again and again and again. I could barely keep from cracking up the whole thing lasted about 15 seconds.

Another thing these are so easy to make that you can make several and lay them around and just watch. Even when people know it is there if it is in a normally very conveniently used place they will keep doing it over as well

i can't get it out

Fotmasta (author)saxophones2009-04-02

It's hard! I stuck a wooden chopstick up the barrel and slammed the hell out of it until it popped out.

Oyarsa (author)Fotmasta2009-04-04

What I do to get them out is to slam the end that you write with onto something and pop the back out. Then take out the ink tube and put it in backwards. Do the same thing to the open end to pop the front out. Then but the end back in.

Capt. Kidd (author)Oyarsa2009-12-10

some bic pen batches have the end cap glued on...

Colonel88 (author)Fotmasta2009-11-29

MY chopstick broke ROFL.

jjanes (author)Fotmasta2009-04-07

Yeah I did run into some that were a bit tight but for the most part they came out might have been the batch I got (I think mine was a twenty or twenty five pack) The chopstick would be a great idea.

Colonel88 (author)2009-11-13

Lol this is more physocological than more straight to the point.

diegolay (author)2009-05-22

Do this: Buy a Red, Green, Pink, Purple or whatever color pen, then buy a pen exactly the same but of a standard color (Blue or Black) I used Red and Blue Pilot G1 0.5 pens then only change the refills and when a friend asks you for a pen or grab it, they'll have a strange surprise

pppoootttzzz (author)diegolay2009-07-30

I've done this before, but only because I ran out of refills that were the right color. It's funny to watch someone's expression when they borrow the pen and write with it.

Squid Tamer (author)2009-04-19

You can make a double sided pen with the remaining pieces!

jjanes (author)Squid Tamer2009-04-22

I actually did this but they never have to take the cap off the pen so it doesn't work to well as a joke unless they are capping it of course but the pen is usable if you do several red and black April Fool Pens you could actually use the double pens one side black and one red ( or blue or whatever)

jjanes (author)2009-04-22

Thanks to everyone who voted I actually one of the three first prize spots .... My office workers better look out... Thanks again I hope you all enjoy this one and good luck to you when you try it on someone yourselves

illdoyourdrugs (author)2009-04-19

This is too basic in my opinion. No shock value. Cant believe this won. Decent ible tho.

jjanes (author)illdoyourdrugs2009-04-22

This might be basic but it really works in many different scenarios and it does make people laugh. Aprils Fools Jokes do not have to have shock value, just be tricky or surprising to the victim when others know whats really going on (ie make them look like a fool thus April Fool). Double remote controls for the same device would also work.... Clear tape over the earpiece on an office phone... Turn a desk around and replacing the items on it in the same positions they were... There are a lot. I have done all of these listed here and all have been great fun Maybe in this case the simplicity helped

3frog (author)2009-04-16

I love it! I am going to do this to my mother in law! She loves pens and this will be a great laugh at Christmas...that's the next time that I will see her! Thanks for the great joke idea!

jjanes (author)2009-04-15

jjanes (author)2009-04-07

coolpizzadude (author)2009-04-01

I just did this to my mom and man did it get her it's the best April fools prank I've ever done.

saxophones (author)2009-04-01

dude this is great!!!! i made it, and did it to my mom, asking for her signature, and she got so confused!!! i love it! best april fools joke ever.

Hudmaster (author)saxophones2009-04-01

I used the same idea. I'm in a hotel, and I went up to the desk with the fake pen, and I asked for their signature, because "I was collecting signatures from everywhere I go." I had to go do something, but when he came back, he had given me another pen, I wish I had gotten to see his face... oh well

MegaMaker (author)2009-03-30

Very good prank.

phreec (author)2009-03-29

great timing...with april fool's day just 'round the corner, and living with 2 type-a personalities... i'm giggling just thinking about it... THANKS SO MUCH!!

RocketPenguin (author)2009-03-29

good job lol

porcupinemamma (author)2009-03-28

Lots of fun. WTG!
BTW, "Wahlah" is pronounced Vwah -lah (spelt "voila") Etymology: French, literally, see there
Thanks very much for sharing your well done instructable! :0) You have a great sense of humour!

Flippy777 (author)2009-03-27

Good idea! I'm going to stuff some pixie stick stuff down the empty pen so the person opening it will have an extra surprise. To plug the lid so dust won't come out I put a little bit of a tissue and jammed it down with a pencil. Great idea!

Flippy777 (author)Flippy7772009-03-27

Oh, yeah you can only do that if you don't use the second end.

benyasbabe (author)2009-03-27

I'm totally doing this to some of the attorneys in my office

C chord (author)2009-03-26

All ready did it but cool

master key (author)2009-03-26


disturbedreaper (author)2009-03-26

this is funny i di somthing like this i just took the point out of the pen and did this also i jam the caps on so they cant get it off but whats fun is when you do both if they ask to borow a pen give them that one they will strugle to get the cap off (dont make it imposible and by this time make sure your out of ear shot) then when they get the cap off they still have nothing to write with
