Monk and Dr. Neven Bell in “Mr. Monk and the Lady Next Door”

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.
