Here are two I remember: Geez, memories, LOL!

Ta ra ra boom di ay
I met a boy today
He paid me fifty cents
to go behind the fence
He knocked me to the ground
His D### went round and round
My mom was so surprised to see my tummy rise
My dad was full of joy to see a baby boy

I know, it’s a bad one, sorry!
The other one is very similar to bzeiger on Sunday, December 5, 1999. Here’s the version I remember:

Fee
Fee fi
Fee fi fo fum

kumala kumala kumala vista
no no no no not to vista
eenie meenie disoleenie
ooh ah ah boleenie
atchy cotchy cumaratchy
ah ah ah

ish kidely oaten boaten
bo bo ba ditten dotten
watten tatten shh!

What that all is supposed to mean or how you actually spell all that, I don’t know. It was just fun to say and as fast as you could!! LOL!!
Any body know the meaning or anything about it?
