>MTV's yo momma came out in 06 so not sure what you mean by 97

Do you think these jokes were invented in 2006?

"Demetrius: Villain, what hast thou done?
Aaron: That which thou canst not undo.
Chiron: Thou hast undone our mother.
Aaron: Villain, I have done thy mother."

That one's from Titus Andronicus, written sometime in the late 16th century.

There's evidence on ones from 3500 BC carved into ancient tablets, but language and culture has evolved too much to be able to get the joke easily. All we know is that the joke involves someones mother, and sex.
