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....)
"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."
