Bowling with bones horror movie or TV show

Sometime in the mid-to-late '80s when I was really young, I saw part of a show that has stuck with me all my life. I don't know if it was part of a movie, or TV show, or what. In it 2 men were bowling in, I think, a run-down castle. They were using a skull for the bowling ball and bones for the bowling pins. Also, one of the men detached his torso from his legs, and the two halves of his body were moving around separately. Can anyone help? Thanks in advance!
