Costume Party At The Asylum

There was a costume party at a mental hospital; the theme of the party was "war". The first person comes up onto the stage and says:

- I'm an atomic bomb.

He gets his applause and steps down.

The second person comes up and says:

- I'm a hydrogen bomb.

Again, there's applause and he steps down.

And then a naked little man comes up to the stage and says:

- I'm dynamite.

Everybody runs away hysterically. When one of them is asked why, he says:

- Didn't you see how small his fuse was?
