Genitals are Funny Frenzal Rhomb

There are some things in nature like
Giraffes when they're having sex that are so funny, it's plain
To see
Some people take offence but my friend Darwin
Agrees with me that god has no might
And science is right
And we're supposedly on top of the evolutionary scale
Most things seem to have them from an insect to a whale
Genitals are funny, they're so funny
Some people of the moral christian right
They fail to see the joke when adam and eve
Removed their fig leaves
The holocaust would have turned out incredibly
Differently if on that dark night Hitler was
Pantsed on sight
And if you can't understand or read the humour in
What I just wrote why don't you take a long hard look
At some testes or a scrote (um)
Genitals are funny, they're so funny
---Middle bit---
Some folk amusement from the telling
Of sexest jokes, they think they're a clown
While they put people down
Why is it that what we're born with is perceived
As awfully crude, would anything be rude if
We were always nude
It's the great equaliser, it renders us the same
And there's nothing quite as humorous as
Pushing up the brain
Genitals are funny, they're so funny
