My first thread - in B4 GTFO, tl;dr. bool story cro, etc...
Let's hear your best April Fool's pranks. This morning, I ran down the stairs in a panic and told my wife "My FullTilt account says $0. I'm freaking out. I don't know if it was hacked or confiscated or what!". She and I both play on FullTilt, and she started freaking out. When she checked her account, I said. "Oh, I know what happened - April Fool's!"
Last year, I had her convinced for about an hour that I couldn't move my right arm - that I had suffered some kind of neurological damage.
I got a pretty realistic looking severed human head, and put it in the toilet face-up before I went to bed. Needless to say at about 3 in the morning, I heard screaming from the bathroom from my roommate's gf.
She actually hit her head pretty hard on the towel-rack after falling backwards which caused a minor concussion, but still worth it imo.
