Quote from Adrian Monk in Mr. Monk Meets His Dad
Adrian Monk: What? I can't just leave. I don't have my toothbrush. I can't travel without my toothbrush. Lieutenant Disher: You can buy a toothbrush. Adrian Monk: Or my pillow case or my Trudy kit or my house. I never go anywhere without my house. Captain Stottlemeyer: You can buy all that stuff, Monk. What you can't buy is another shot.
