Stottlemeyer: During your stay your name is Frank Conoway. Here's your ID.
Monk: But this guy doesn't look like me!
Stottlemeyer: Monk, that's a picture of you.
Monk: (Pause) It is?
Natalie: You're the Prince of Darkness!
Stottlemeyer: Nah, nah. He's not the Prince of Darkness. I've seen him vacuum the ceiling. The Prince of Darkness wouldn't vacuum the ceiling.
Monk: I've got Nature--Nature on my hand! I need a wipe.
(Natalie hands him a leaf)
Monk: You can't clean Nature with Nature!
