What are some Jo mamma jokes?

"Yo mama" jokes are a form of humor that play on exaggerated characteristics or situations involving someone's mother. For example, "Yo mama is so big, when she skips a meal, the Stock Market drops!" or "Yo mama is so old, her birth certificate says 'expired'!" These jokes rely on hyperbole and are often meant to be light-hearted and playful, though they can sometimes tread into offensive territory.
