These are some of the classic "Dozens" street jokes that people use to dis each other's mothers.
More love for your momma...Your momma's so poor I saw her kicking a can down the street and asked her what she was doing and she said "Moving." Your momma's so old I told her to act her age and she dropped dead. Your momma's so ugly they wouldn't let her into "Friday the 13th" because they were afraid she'd scare somebody. Your momma's so fat when she's on a diet, she just orders the left side of the menu. Insult all your friends!
