A: I can't understand how you can live so happily here, at the death row.
B: The truth is that I know something they don't.
A: What is it?
B: Well, I'm actually dead. I died some months ago because of a nasty diarrhea, but they haven't noticed it yet... So they can't kill me again.
A: But what will they do to you if they find out you're not alive?
