Old Man's Peanuts

An old man and a young man work together in an office. The old man always has a jar of peanuts on his desk, and the young man really loves peanuts. One day, while the old man is away from his desk, the young man yields to temptation and scarfs down over half of the contents of the jar. When the old man returns, the young man feels guilty and confesses to his crime. "Don't worry, son. I never eat the peanuts anyway," the old man replies. "Since I lost my teeth, all I can do is gum chocolate off the M&M's."

Yo Mama - Teeth

Yo mama is so old, her teeth are like stars: they come out at night.

Yo Mama - Buck Toothed

Yo mama so buck toothed, when she bowed her head to pray, she bit a hole in her chest.
