Good prank if you fall out with your neighbor.
If its usualy Dark whem they get home, stick a drawing pin to the handle of their garden gate, right where you would put your thumb if you were to open it. Next smear a little (animal of your choice) faeces on and around the drawing pin! When he/she opens the gate they will prick their thumb on your drawing pin and instictively suck their thumb as a result....!
Friends of mine at duchy college managed to dissasemble an International 1486 and then reassemble it in their lecturers office in the space of a weekend and with the help of the caretaker
When I stayed at my Girl Friends in uni halls, One of her flat mates (who was a complete tosser) went out and got Blind drunk, so while he slept, we covered everything in his room in newspaper, then made his phone alarm go off. He was seriously not amused, ooops
Oh, and on the last day of sixth form, we put squid down the back of the radiators in the common room, and in the hollow space above the ceiling...
So many others that I feel would not be 100% appriciated by some of the more grown up and mature members of the forum!!
