I first found this list on a BBS around about 1993 and it’s still floating around! It’s still as good as it was back then too – some of these are far out!

8. Learn to levitate. While your roommate is looking away, float up out of your seat. When s/he turns to look, fall back down and grin.

42. Put your mattress underneath your bed. Sleep down under there and pile your dirty clothes on the empty bedframe. If your roommate comments, mutter “Gotta save space,” twenty times while twitching violently.

53. Clip your fingernails and toenails and keep them in a baggie. Leave the baggie near your computer and snack from it while studying. If s/he walks by, grab the bag close and eye him/her suspiciously.

64. Create an imaginary cat for a pet. Talk to it every night, act like you’re holding it, keep a litter box under your desk. After two weeks, say that your cat is missing. Put up signs in your dorm, blame your roommate.

106. Pretend to shower often but only wash your hair in the sink. See how long it takes your roommate to notice.

129. Get your roommate’s social security number. Call the registrar and switch all of his/her classes. Tell your roommate at the end of the term that the Philosophical Environmental Anthropology exam is supposed to be really hard. Wish him/her luck.

193. Move everything to one side of the room. Ask your roommate if s/he knows how much an elephant weighs, and look at the floor on the empty side of the room with concern.

229. Keep some worms in a shoebox. When doing homework, go and consult with the worms every so often. Then become angry, shouting at the worms that they’re stupid and they don’t know what they’re talking about.
