Quote from Adrian Monk in Mr. Monk and the Psychic
Sharona: You really think he forced his wife off the road? Adrian Monk: Yep. Sharona: Any idea how? Adrian Monk: Unless I'm crazy, he put something on the road that sent her over the side. Now, that was the easy part. The hard part came later. Sharona: What's that? Adrian Monk: Getting that loony tune, Dolly Flint, to find the body. That's the real mystery here.
