Your Best April Fools Prank

I want to hear about your best April Fool's Day prank!

Mine was years ago when my husband came home from work. He was greeted by a crumbled newspaper cascade, my fake black eye, a buttered toilet seat, and a sugared shower floor. Mmmmm good times. ;) I don't think I'm into pranking much now, but I would like to know about your best prank. Please share your best fooling on this day, in my comments section.
