First we started on "Yo Momma" jokes. Here's a few:
Yo momma's so fat that she snores when she's awake even with Breathe-Right strips. (ready)
Yo momma's so stinky that when she walks to the dump the garbage runs away. (ready)
Yo momma's so dumb she lost her legs... and she puts her prosthetics on the wrong legs (i.e right leg on left stump. Needs work)
Yo momma's so fat and white and old (white hair) that if you put a snowball or a scoop of vanilla ice cream on her head she looks like a snowman. (could be improved. should the snowball have a carrot in it? how can this be more logical?)
Yo momma's so ugly she slapped herself when she looked in a mirror because she thought she was spanking a butt. (i.e her face looks like a butt. works?)
Please use this to get your own jokes started. Send them in!
