Paranoia is funny when verbalized.

Transcript of Thief's rant:

"Well, we could set off a trap of some sort that vaporizes us, or we might just cause the world to end. Some calamity may wind up stealing out souls, or we could step on a land mine from some long forgotten war. Or, we might be trampled by an elephant on a rampage, or-"

Come to think of it, that's actually pretty similar to Kheros' speech in Cooler Ways to Die.

I must be pretty good at thinking up things that can go wrong.
