The Private Navy of Sgt. O’Farrell (1968)
LOL. I was just thinking of the same movie. Saw it way back then at the base theater.
This is EXACTLY the movie I was thinking of. I remember seeing as a kid. Phyllis Diller had the hots for the Bob Hope character and they used CO2 bottles to cool the beer, which you had to have a church key to open. Classic!
