"Since today is April Fool's Day in the USA, what is the best prank you have ever played on someone OR that someone has played on you?"
My answer is short and sweet because I have never had an April Fool's joke played on my, nor have I ever played one on someone else. Well, unless you count the students at school who come in every April 1st and say "There's a bug in your hair! April fools!" or "Your shoe's untied! April fools! Of course, as a teacher I feel obligated to look down and laugh, but really April Fools Day in my world is one long string of "tricks" that are older than me (which, of course, the kids think they made up-adorable).
