my dad used to sing this to us, slightly different version, back in the 1950's

I went to the animal fair
The animals all were there
The big baboon by the light of the moon
Was combing his auburn hair
The monkey, he got drunk
And sat on the elephant's trunk
The elephant sneezed
And fell on his knees
And that was the end of the monk, the monk, the monk.

it was a big favorite of ours... lol and the only way to stop my brother's incessant "you wonder where the yellow went, when you brush your teeth with Pepsident"... aaahhhhh!!!!
