Hang up teabags outside someones room. It's excellent to do this to your roommates for an extended period of time, eventually they will lose it! You'll see :)
Each and every time you get the opportunity tape a teabag so it hangs outside one of your housemates rooms at about head height.
Sounds pretty innocent but after 6 weeks of constantly walking into teabags, you're victim will go crazy!
