Dozens (game)

Yo Mama jokes probably originated in African-American stand-up comedy.

Yo Mama is so fat...

• when I said it was chilly outside, she grabbed a spoon and ran out the door!
• when she hauls ass, she needs help!
• when she wears a red dress, people yell "hey, Kool-aid!"
• her favorite food is seconds!
• when she goes to the zoo, elephants throw HER peanuts!

Yo Mama is so old...

• when God said "let there be light", she flipped the switch!
