There's nothing creepier than a creepy doll, particularly if they're not expecting it. Put this little guy in your roomie's sheets and enjoy watching the scream as he pulls them back at bedtime. Truth told, though, odds are they won't be able to sleep even after it's gone.
2. A Dildo
There's very little funnier in the world than dildos because hey are, afterall, fake dicks. Surprise your roommate buy hiding one of these guys in their bed, and watch them struggle to figure out how to dispose of it. There is no dignified way to deal with a dildo.
The most famous instance of hiding something in someone's bed is definitely that scene in The Godfather. While real horse heads are hard to come by (and possibly illegal) you can still do the next best thing and get your hands on one of these creepy looking masks. The best part is that after you scare your roommate by hiding it in their bed, you can scare them by wearing it around the house.
This one is a classic. Get yourself a big, fake spider and even the bravest of roommates is sure to squeal like a scared little child. It's believable and that's what makes it scary.
5. A Doodoo
Another classic. Nobody likes dookies, especially in the place that they sleep. In the time it takes your roommate to realize it's made out of rubber, you'll be laughing so hard you make a real one of these in your pants.
This is the next best thing to planting actual evidence in your roommates bed. Give them the shock of their life as your roommate rips back their sheets and breifly contemplates their own sanity and tries to remember if they killed someone.
Pranks don't have to only have to be scary or gross. Confusing your roommate can be equally fun. Leave a copy of this 2007 Best Picture nominee and watch as your roomie writhes around in confusion, trying to figure out how it got there. It's just believable enough that they may not immediately assume it was your doing.
Finding a pair of unfamiliar underpants in your bed instantly tells a horrifying tale. Making them a weird pair of underpants puts a twist in the narritive. Laugh on as your roommates imagines the worst. It will be the best.
You don't have to limit yourself to hiding things under your roommate's sheets. Install this bad boy above their bed and have them think you've completely violated their privacy, without the legal ramifications of actually violating their privacy.
10. A Fake Spider, A Horse Mask AND A Dildo At The Same Time
Your roommate won't know what hit them.
