I know a drummer and a guitarist
who in times gone by, played in various local bands. There was a certain amount of jovial rivalry between them and this was played out in various pranks that started out by a group of us shovelling freshly fallen snow to cover the back door of the drummers house. 8 feet high and about 4 feet thick at the bottom. His mum, on opening the door, went ape. So to get his own back, George, the drummer involved, took all his broken drumsticks, and 'planted' them in the flowerbed of (Ben*)the guitarist's house, and stuck a head of a freshly killed pheasant on the end of each stick.
Cue the most ugly photograph of Georges face, looking like he had something inserted rather hastily up his bottom, photocopied and plastered all over town. To get his own back, George covered Ben's plastic Pig (Reliant Robin for all the non UK persons here) with Vaseline and then graffittied the whole thing. No damage done the whole lot could be hosed off in a trice, but Ben was mortified when he first saw it.
Now it gets rather dangerous, Ben bought himself about £5 worth of fireworks (yes nearly a year later, and tied them to a bamboo pole, the like that used to come in the centre of a carpet before the long cardboard tube, lit them and placed them near the window of George and his girlfriends bedroom, in a very old pub.

Attempted arson was the charge.

*Name changed as Ben is now a very accomplished guitar technician for some very global Muso's
