identify this movie - WW II romantic comedy with the line "Thanks for the add"

I'm racking my brain trying to remember an American made (ca. early 1940s?) war film about Americans at war, perhaps with some romantic comedy aspects to it.
Main reason for interest: Mess scene in film where NCO says, "Thanks for the add".

Most people assume that the expression is very recent with its origins in internet lingo (for e.g., in MySpace), but evidently it goes back way beyond.
