The Mcdonalds Cup Prank.

This Prank enables you to make someone make a fool out of themselves just simply trying to drink a drink.

You will need:
 An empty drinks cup with a lid and a straw.
 A sharp pencil or something similar.

Step 1: Step One.

First take your empty cup and place upside down. Now roughly mark the centre of the base with your pencil or sharp object. When you have done this peirce the hole you have just marked to about the same size as the diameter of the drinking straw.

Yep, I can almost see my wife helping herself to my drink, but no one else, and I'd have to be pretty stupid to prank the person next to whom I sleep at night.

Also, if you picked up a cup of liquid and tried the straw and got nothing but air, aren't you going to suspect something?  This is a funny idea, but I'm just not seeing it actually working on anyone you'd want it to work on.

I think that if you plug up the end of the straw it would be more effective.  Just make sure that you plug it with something that the victim can't accidentally suck up through the straw and choke on.

Duct tape!

How about just putting a piece of duct tape on the end of the straw and putting it back in the drink? No hole to worry about.

For even more trickiness, keep some of the drink in the straw before you seal it, then squirt some ketchup in it! Bleck, runny soda ketchup!

A prank I like to pull on friends is to tie the straw in knot and put the knotted end into the liquid.  When they suck on the straw they get nothing.

Why would someone drink from a McDonald's Cup that they didn't purchase. Is this prank exclusively played on the homeless?

Get another empty cup, empty their drink into it, proceed with 'ible, refill cup. All you need is a little initiative : )
