Hi Nick, welcome to the forum.. :)

I don't have any MASH quotes on the site, but I belive the motto they used for 4077 MASH was "The best care anywhere" :D
I just found one but it is the only funny one...

Frank: I'm a pretty fair doctor myself. Ask any of my patients!
Hawkeye: We can't dig people up just for that.
Col Potter: "Klinger! What are you doing?"
Cpl Klinger: "Eating a jeep what does it look like I'm doing?"

Cpl. Klinger to Sgt. Rizzo:
"If my dog had a face like yours, I would shave his butt and teach him to walk backwards!"
When Margret was "leaving" (I think the episode was called "Hot Lips and Empty Arms") Peirce paid her a goodbye visit: "They fighting is a form of loving. I guess we've loved you as much as we could without actually killing you." (I think it goes like that anyway....)
And one of my favorites from Hawkeye...

"I will not carry a gun, Frank. When I got thrown into this war I had a clear understanding with the Pentagon: no guns. I'll carry your books, I'll carry a torch, I'll carry a tune, I'll carry on, carry over, carry forward, Cary Grant, cash and carry, carry me back to Old Virginia, I'll even 'hari-kari' if you show me how, but I will not carry a gun."
