There were two variations of this chant at my school:
Bang Bang you're dead
brush your teeth and go to bed
and
Bang Bang you're dead
fifty bullets in your head
Googling around shows that both (or a combination of the two) are fairly well known, though I can't quite find anything that might indicate how far back they go. I can't find either of them in print, though "bang bang you're dead" by itself was a common cry by the middle of the 20th century in war games all over the country. No telling where the rest of it came from, though I imagine that it's been around a while.
There are plenty of variations after the "fifty bullets" line, including "some are red, some are blue / some are made of chicken poo" and "another one / up your bum"
Where and when did YOU hear this one?
