Quote from Adrian Monk in Happy Birthday, Mr. Monk
Natalie: Another murder. Coincidence? Captain Stottlemeyer: I don't believe in coincidence. Okay, let's take a step back. We got a janitor who's killed. The only other guy in the building is a lawyer named Richard Meckler. Ten hours later, Meckler is poisoned. What do you think, Monk? Adrian Monk: I don't believe in coincidence either. And I also don't believe in surprise parties. [opens morgue drawer] Natalie: He has a big birthday tomorrow. Medical Examiner: Happy birthday.
