Nonsense Rhymes, Tongue Twisters and Limericks

[Ojisama]

This thread is for all those nonsense rhymes you heard when you were a kid. Some may be by famous people, but if you can't remember their names, so what. We'll just assume that somebody, somewhere made it up

I'll start.

One fine day in the middle of the night,
Two dead men got up to fight.
Back-to-back they faced each other,
Drew their swords and shot each other.
