Yo mama so fat when she jumped in the water, the whales started singing "We are a family, even though you fatter than me."
Yo Mama is So Fat Even Whales Sing About It
Explanation
This is a classic 'yo mama' joke where the humor comes from exaggerating the mother's weight to an absurd degree. The joke implies she is so incredibly large that even whales, known for their size, feel the need to point out that she is fatter than them and declare it by singing a song.
