Chris and I have been making a few mathematical yo mama jokes. I thought that this was a topic worthy of a forum thread. Any good things that arise can go in The Mathemagician, for want of better stuff.

Let's kick off with "yo mama's so fat that she has no room to move in the discrete topology".

Yo mama's so dumb she thought the harmonic series was a music festival

I just wanted to post before it gets locked. Everyone else post quick, before it's too late.

Anyone who does not post before it gets blocked actually has a mama as described in this thread!

Yo mama's so fat, even a forgetful functor can't forget it.

Not even if it's as dumb as yo mama.

I guess I'll drop in the well-known and loved

Yo mama's so fat she has a proper subset isomorphic to herself

Oh yeah, well yo mama's so fat, her collection of fatty tissue cannot be formulated as a set. It's a proper class.

yo mama so dense, the closure of herself is everything
