heres a kinda old one yo mama is just like burger king. "have it your way" or this one is stupid your mama is so old she ran track with the dinosaurs lol.
Let's see. My best yo mama joke has a curse word in it so I'll change it. You may notice it.
Yo mama is so ugly, when Michael Jackson's kids saw her, they said, " Oh crap, daddy broke out of jail. ". Yo mama is so stupid, she put a lamp on her TV and said she had sat-a-lite.
