I used to super glue a quarter to the floor out side the bosses office. I took extra delight watching her break her finger nails trying to pick it up.
Another one of my favorites was putting Saran Wrap over the toilet in the McDonalds... Put t he seat down, then tie plastic bags on the wall urinals... Then I'd go have a big mac or two... The guys came out SOOOO pissed off.
I found it even more funny that not one of them "Broke" the wrap for the next guy...
Do any of you have a prank planned this year? What was your best prank ever?
