Quote from Captain Stottlemeyer in Mr. Monk and the 12th Man
Lieutenant Disher: Captain. Washington just sent this down. It's a prelim psych profile. Captain Stottlemeyer: Let me guess. The killer is between 30 and 45 years old, white male, does not work in an office, probably spent time in the military and definitely hates his mother. Lieutenant Disher: Yeah. How'd you know? Captain Stottlemeyer: Because that's what they always say. That's scrap paper.
