...sounds like you're thinking of the riotous 1967 comedy, "Who's Minding the Mint?", which starred Jim Hutton and Milton Berle...
I was going to say the same thing as Fright Film Fest. I remember seeing "Who's Minding the Mint" when I was a kid and I always thought it was a great movie, but I don't remember much about it. Would love to see it again.
