Yo Mama So Slow

Listen up, buttercup. This joke is all about comparing how long it takes to do something, right? Well, the joke says "yo mama" is so slow, it took her nine months to come up with a joke – that's how long it takes to bake a kid in the tummy, see? But the joke teller? Oh, he's much faster, only took him six months to tell a joke. It's like saying your mama's slower than a snail glued to a rock, which you probably resemble.
