Culturally speaking - What is the funniest Mama joke you know?

[Neo Draven]

And, is it funny because it's racist, a fat joke, an old joke; what about your favorite Mama joke makes it so funny to you?

My personal favorite of all time is an uncommon one that doesn't fall into the same 'so black', 'so white', 'teeth so yellow', 'so fat', 'so old' category.

Yo mama got bifocals so thick, she can look at a map and see people waving.
