Another version of the male and female exchange is:

Onto the bed and roll over!
No! No!
I said onto the bed and roll and roll over!
I'll be f***ed if I roll over.
You'll be cornholed if you don't!

I knew the "nail your other foot" type jokes as little Johnny jokes.

Mrs. Jones, can little Johnny come out and play baseball with us?
Now you know little Johnny has no arms or legs.
That's OK. We want to use him for first base.

Mrs. Jones, can little Johnny come out and play tag with us?
Now you know he has leprosy.
OK, so can we come in and watch him rot?

Where did you get that iron pipe?
From little Johnny's iron lung.
What did he say?
Uuuu

And the cruelty jokes go on and on, a way to handle the worst that life can fling at us by making it lighthearted.
