Needed - Small wad of brillo pad.

When friend is out sneek into his room. Take his lightbulb out (power off!). Stick brillo into socket. Leave. When friend switches on light the brillo acts like a fuse and blows up(small flash and quite loud noise). Be careful with this one, it has been known to knacker the odd light switch.

Needed - Cayenne Pepper. Electric Cooker.

This is a very good one. Sprinkle a good dose of the pepper on the ring element. Turn the ring on and leave the room, shuting the door behind you with your friends in the kitchen not looking at the cooker (this is easy if you have a joint kitchen living room, wait till they are watching TV). This will result in the pepper burning into the air and your frends eyes streaming and throats burning.

In our student hall we had those cheapo carpet tiles. When a friend went away for a long weekend, his `drinking pals' broke in, flooded his carpet and spread about a sack full of cress seeds. One hour before he returned they `borrowed' a sheep (fromm agric. or vet. -- I can't remember) and put it in his room to grazed. The they then set up0 a camera to take a picture of the surrounding scene 3 seconds after the door was opened. You've never seen such a funny expression.

My cousin told me about a practical joke some of his friends played where they had a white horse on the hill within view of their halls of residence (this is one of those large white horses done in chalk on hillsides - there are several in England) - they "painted" it with black stripes one night so the next day it was a Zebra. ( I think they actually used black plastic bags)

Years ago when I still lived (and went on my bike to work) in Bucharest, Romania, I was often sprayed with mud by car and bus drivers who felt a sadic pleasure by doing this. I used to note the license plates of the culprits and in four instances I spotted those cars parked on streets not too far from my home. I provided to their owners several mornings of hard work to remove newspapers stuck on their windshields with a very good glue. In one instance I filled the exhaust pipe with wet cement... In all cases I left a note with "thanks for the shower".

The best practical joke that we pulled was pulled on my friend's floor's busybody. I showed up at his dorm, went into his room, and proceeded to yell at him (my friend). He yessled back, and we got into a heated arguement. Eventually, I fired a few blanks, which this busybody was sure to hear. I then ran from the room, and when the busybody went to look, he saw my friend lying in a pool of blood (we used fake stuff). When he went to call security, my friend quickly changed his clothes and put a rug over the "blood" on the floor. When the cops and the campus rent-a-cops arrived, my friend was sitting quietly, studying. It was suggested to the busybody that he take a nice long break from college to let his nerves recover.
