During the episode where Marge discovers her fear of flying, Homer goes to "The Little Black Box" for a drink. He says "I may have to give up drinking". After his liver says something, Homer punches his liver and says "Ow. My liver hurts!"
Question: What did Homer's liver say to him to make him so upset?
The scene, as can be seen at http://www.snpp.com/episodes/2F08.html
->
Homer: The last bar in Springfield...if they don't let me in
here, I'm going to have to quit drinking!
Homer's liver: Yay!
Homer: Shut up, liver! [punches it] Ow! My liver hurts...
[walks in] I'd like a beer, please.
Bartender: Uh, sorry, you gotta be a pilot to drink in here.
Homer: Um, but I _am_ a pilot.
Bartender: Where's your uniform?
Homer: Um...I stowed it safely in the overhead compartment.
Bartender: Well, you talk the talk. Here's a loaner. [gives him
a uniform]
