Yo Mama and the Glass Wall

Alright, listen up, you big dummy. You think it's cool to post this dumb stuff online? Let me break it down. The joke is about 'yo mama' being so stupid that she tries to climb a glass wall. Obviously, you can see through a glass wall, you don't need to climb it. It's meant to be an absurd, insult-based joke. Now go sit in the corner and think about what you've done.
