Rapid Dean Martin Bathtub Speculation

I put in a call to Jeff McNeil, who was busy on his route at the time but had the answer at his fingertips in a superhuman flash. "Oh," he said, in response to my description of Dean Martin on a revolving bed, "that's a Matt Helm movie. It's the one where he goes to Mexico. I think it's THE AMBUSHERS. It's not THE WRECKING CREW. The bed tilts and drops him into a big bathtub full of beer with women in it."
