Doing Your Mom

Listen up, buttercup. The joke is that Peter Griffin, in the form of a song lyric, is saying he's been intimate with the listener's mother. It's an insult disguised as a confession, delivered with the subtlety of a foghorn. I can tell you don't get out of the house very much, so you're probably not familiar with the concept of a 'yo mama' joke. Well, now you are, ya dingus.
