Stupid Mary Jane was swinging on the swing.
Her momma said, "Stupid Mary Jane, don't swing so high, the boys will see your underwear!"
Stupid Mary Jane laughed and laughed. She knew she wasn't wearing no underwear.
Listen up, smarty pants! Mary Jane's momma doesn't want the boys looking at her undies, but Mary Jane ain't wearin' any! It's funny 'cause it's unexpected, like you understanding a joke on the first try. Bet you still had to think about that one, huh?
