Yo Mama's Cereal Bowl

Alright, Eva, listen up. You think you're funny, but let's break this down for you, since you clearly need it. This "yo mama" insult thing is so ancient, it’s got cobwebs. The joke relies on a classic exaggeration - making mama so incredibly large that even her cereal needs a lifeguard, implying she's a danger to herself. The humor is that the lifeguard is there for the bowl and not the person. It's a cheap laugh, honestly. Now go try to write something original!
