Eagle's Joe Mama Insult

Listen up, you goofball! The joke is playing on "yo mama" jokes. The eagle says "Joe Mama" which sounds like "yo mama". It's funny because it's unexpected and kinda childish, which I know is right up your alley. Plus, it involves Obama, so it's topical, even though I bet you think topical is a cream you put on your rash, which, let's face it, you probably have.
