Quote from Captain Stottlemeyer in Mr. Monk and the Very, Very Old Man
Adrian Monk: This security guard. George Rowe. Look at the signatures. This is Monday, the day of the murder. Captain Stottlemeyer: Right. Adrian Monk: These two are from last week. Captain Stottlemeyer: Yeah, that's a pretty good match. Adrian Monk: Not the handwriting. Look at Monday. He misspelled his name. Captain Stottlemeyer: Son of a bitch. How did I miss that? What is wrong with me?
