Yo momma's so stupid, she steals samples from stores!
Yo mamma so stupid she put two M&M's in her ear and said she was listening to Eminem.
Yo momma's so fat, when she went to the beach, the whales sang, "We are family!"
Yo momma so dumb that when she was locked in a grocery store she starved!
Your momma is so stupid she put airbags on her computer in case it crashed.
