Columbo, Season 1

Flemming:
You never stop, do you?

Lt. Columbo:
What?

Flemming:
The insinuations, the change of pace. You're a bag of tricks, Columbo, right down to that prop cigar you use.

Lt. Columbo:
Oh, come on, Doc.

Flemming:
I'm going to tell you something about yourself. You think you need a psychologist. Maybe you do, maybe you don't, but you are a textbook example of compensation.

Lt. Columbo:
Oh, what, Doc?

Flemming:
Compensation. Adaptability. You're an intelligent man, Columbo, but you hide it. You pretend you're something you're not. Why, because of your appearance you think you can't get by on looks or polish, so you turn a defect into a virtue. You take people by surprise. They underestimate you. And that's where you trip them up.
