Mouch and Severide in “Unfinished Business”

Mouch

A firefighter brother recently asked me, what makes a good squad guy. He said, "Hey, Randy McHolland, what makes––"

Severide

[interrupts Mouch] Hold up, hold up. Mouch, why do you keep referring to yourself in the third person?

Mouch

Ok, look, I'm trying to subtly reinforce my real name so you guys start calling me that. 'Cause now that I'm interim president, I don't think a nickname that means "half man and half couch" is appropriate anymore.

Severide

Then why don't you just say, hey guys quit calling me Mouch.

Mouch

You're right. I should've.
