Back when I still lived in the West over a summer...
First one morning I woke up to find a scooter on top of my car... I was fucked, couldn't get the scooter down or drive the car..

So after I found out who did it with a friend we bought several hundred pounds of dry dog food, while he was at work we got one of his colleagues to give us his keys, and filled his car to the brim with dry dog food... should have seen his face...took him forever to take that shit out weeks later you could still find some in his seats...there was a few other pranks in the middle ..just remember it ended with us emptying the whole content of his house and spray painting the outline of the objects we took on his front lawn.
