Quote from Adrian Monk in Mr. Monk and the Dog
Adrian Monk: Did Amanda wear glasses? Samantha Austin: No. Adrian Monk: [picks up glasses case] Somebody wore glasses. Was she dating? Was there anyone in particular? Samantha Austin: She didn't say. She never did. She's a pretty private person. Adrian Monk: [looking at painting] Are those glasses? Captain Stottlemeyer: Looks like it. Did somebody pose for this? Samantha Austin: I don't know. I think it's new. Natalie: Could be a lover. Adrian Monk: How do you figure? Natalie: Well, he's naked, and... Lower right corner? Adrian Monk: Oh. Oh. I thought that was the signature.
