Buttercup: We'll never succeed - we may as well die here.

Westley: No. No. We have already succeeded. I mean, what are the three terrors of the Fire Swamp? One, the flame spurts. No problem. There's a popping sound preceding each, we can avoid that. Two, the Lightning Sand. But you were clever enough to discover what that looks like, so in the future we can avoid that too.

Buttercup: Westley, what about the R.O.U.S.'s?

Westley: Rodents of Unusual Size? I don't think they exist.

Learn from Westley's naiveté and don't underestimate the unknown! Especially when opining about such monstrosities!
