Monk, Season 7

Monk:
What's the catch?

Dr. Neven Bell:
With what?

Monk:
With Marge, what do you suppose she's after?

Dr. Neven Bell:
Uh, Adrian-

Monk:
Every time somebody wants to be my friend, it turns out they're after something. They have an angle!

Dr. Neven Bell:
Not necessarily.

Monk:
How could somebody - how could anybody - love me unconditionally? I mean, come on, you met me!

Dr. Neven Bell:
Adrian, I know you've been burned in the past, but you have to trust people. See, there's not always a catch.

Monk:
Then how do you explain this? There's always a catch.
