Anya and Xander in “Entropy”

I wish you had tentacles where your beady eyes should be! I wish your intestines were tied in knots and ripped apart inside your lousy gut!

They are.

Really? [brightening] Right now? Does it hurt?

God, yes. It hurts so bad it's killing me. Anya, I love you. I want to make this work.

Those are... metaphor intestines! You're not in any real pain!
