Face: But Hannibal, rules are made to be broken!
Hannibal: Noses are also made to be broken, right, Face?

Face: I'm allergic to bullets. Especially those headed into my direction.

Face: The bigger they are, The harder they fall.
B.A walks into the room
B.A: The bigger they are, the harder they hit!

Face: You better watch my back.
Murdock: Who's gonna watch mine?
The walk across the room.
Murdock: Face, your back. It's looking good.

Murdock: [sings] I'm a lumberjack, I'm ok. Sleep all night and then work all day. Wear my clothes just once a year. Smells real bad but I don't care. I'm a lumberjack, that's a fact.

Shawn: Mr. Murdock, welcome to your new studio.
Murdock: I don't get it. I've already got a studio. My studio and I go back a long way. Long before home personal video cassette recorders.
Shawn: While you're under contract with the gallery, this is your studio
Murdock: You don't seem to understand! I need my studio! I trained inspiration to find me at that studio! Now, how is it going to find me?
Season 4

A tree falls on Murdock.
Murdock: [sings in pain] I'm a lumberjack, I'm ok. I got no legs, but what the hey.
Hannibal: How are you doing, Murdock?
Murdock: I think there is a tree on my leg.

[B.A. and Murdock were attacked by one of Boyle's men]
Hannibal: You're sure it was one of Boyle's men?
Murdock: Absolutely. It was that guy, Lupis. He's about 6'3', built like a bathtub.

Face: You want me to pick up WHO?
Hannibal: Eh ... Lupis. He works for Boyle. We saw him yesterday.
Face: Oh, yes. It's the big one, about 6'4', built like a chest of drawers?
Murdock: Yeah, that's the guy, guy. And you be careful. He almost killed B.A. He's at least 6'5', 240.
Hannibal: Now, I'm gonna check out his office. You check his house. If the guy Lupis shows, bag him.
Face: Wait, the guy's 6'6', 250 pounds. He almost killed B.A., and you want ME to bag him?
Hannibal: Sure.

[Murdock acts as if he was a crazy boss who is being threatened by some guys]
Murdock: Nobody comes in here and threatens me under my own roof. Especially when I'm eating a tuna-fish sandwich.

[Murdock pretends to be a crazy painter and brought off a deal. His partner wants to shake hands]
Murdock: Murdock does not shake hands, Murdock does not play sports, Murdock does not open canned food. Murdock paints.

Murdock: [holds up a pizza] Let us break pizza to cement the bargain.
