I used to play in a crowd of kids and there was this one little boy who would pick up used bubble gum and eat it - this is in the good old bubblicious days!
Anyhoo, one day we found a couple of lumps of bubblegum on the streets and stuck a small worm in the middle and gave it to this boy who promptly munched away on it - much to our hilarity. He must have been about 4 or 5 and we were big grown ups of about 9 at the time.
I do feel a bit guilty about it now, but at the time it was great!
p.s. what have you done to make everybody hate you?
