Yo mama is SO FAT... SO FUCKING FAT... That when she went on the bus, she wasn't allowed in. She asked why, and the driver pointed to the sign "Weight capacity of 50 people". The bus was empty.
She got mad and ate the bus!
Listen up, dummy! This joke is all about how fat yo mama is. She's so gigantic that she can't even get on a bus that's supposed to hold 50 people. And get this, she's so mad about it that she eats the whole dang bus! Like you're eating all these cheeseburgers, you probably have a similar problem.
