These are some of the classic "Dozens" street jokes that people use to dis each other's mothers.
Try these out on your friends...Your mother is so fat, when she puts on a pair of BVDs, by the time she's done they spell "boulevard." Your mother is so fat, when she sat on a quarter, a booger came out of George Washington's nose. Your mother's so fat, she earns extra money selling shade in the summer. Try 'em on your own mother!
