I'm trying to identify a science fiction TV show I saw in the early-to-mid 1980s or late 1970s. This story was a self-contained episode, so it was probably part of a Twilight Zone-like anthology series.
In the story, a man wakes up from cryogenic suspension in a future hospital. He is generally rude and makes unwanted passes at the nurses. He is anxious to leave the hospital, but the doctors tell him he must stay for more medical tests.
A nurse wheels his gurney into an elevator to take him to a lab upstairs. In the elevator's reflective ceiling, he (and the viewer) learn that he is just a head! He screams, realizing that his head had been frozen without his body.
The closing shot shows his head on a lab shelf with other heads. He is shouting for help as the other heads try to introduce themselves to the new guy.
