Dan and Dr. Cox in “Unfinished Business”

Dan

[Objecting to Dr. Cox's harsh treatment of a patient] Dude, these are living breathing people we're talking about here-

I'm sorry, Dan, what do you do?

Dan

I tend bar.

Well, how about you let me worry about the way we do things around here, but if I ever do need advice on how to make a top notch rum and Coke, well then by gum mister you had better be by the phone cause I just might give you a jingle. [mimes talking on a phone] "Bah-rrring! Hello, Dan? Cox-a-roonie. Regarding the rum and Coke issue. Couldn't be more confused."
