Can anyone tell me in which episode this quote was?

Major Healey: "Well when you get married everyone is going to want to meet your wife, right!"
Major Nelson: "Yes"
Major Healey: "Well I can see it now. Does your wife smoke? Yes. What brand? No she doesn't smoke she just smokes. Excuse me guys while I just get my wife out of the bottle. Oh Dr Bellows is going to love that one."

I can't remember, and it is driving me crazy!! Thanks!
