Thank god he wasn't around on April Fool's last year, but I had a friend named Jack (he played a Ret Pally in Wow so...) who was/is a batshit bonkers asshole who used to hang out around my apartment all the time. He was known for pranks and generally stupid shit and never shied away from doing things to poor old me. Examples:
1. Shit in a dixie cup and put it under my bed
2. Found a dead possum and put it in a coffee maker box, knocked on my door at 3 am and left the box sitting in front of the door upside down
3. Moved all of the furniture out of my room, including TV and Xbox, out into the courtyard and sat on my bed playing Guitar Hero (thanks to a long ass extension cord).
So yeah, in almost all those cases I responded with, "fuck you."
