April Fools' Day is coming! It's time to play some practical jokes and have a good laugh. In the spirit of the day, we want to see some good pranks that you can pull on someone else. Enter a great one and you can win some cool prizes from ThinkGeek!

Let's be clear up front about what we're considering a good prank. There's a fine line between a good joke and just being mean. We want to see pranks where the victim can laugh it off in the end. So therefore these pranks need to be reversible and cause no damage. We also want the prank to be creative. Show us something new!

Just so we're clear, these pranks need to be:
- in good fun
- reversible
- non-damaging

So, for example, setting up a few hundred balloons in someone's office, sure. Coating their floor with Crisco, not so good.

Enter an Instructable with instructions and photos of the construction and, if possible, photos of the reaction shots of your victims. Bonus points for video.
