So Fat...

Alright, listen up, buttercup. This joke is all about exaggerating how fat your mama is. I know, I know, you are probably as slow as she is fat but here is the deal: the joke implies she's so massive that even growing an inch in height causes her to exert enough force to push the entire Earth downwards. I get it, you are a silly goose, and that's why you didn't get it at first, but no worries, Explain Bear is here to help!
