Yo momma's so fat, she tripped over Wal-Mart, stumbled over K-Mart, and landed on Target.
Yo mama so stupid, she got hit by a parked car.
Yo momma's so ugly she makes the blind go crippled!
Your momma is so stupid she put airbags on her computer in case it crashed.
Yo mama so ugly she gives Freddy Krueger nightmares.
