Private Dancer - October 6, 1979 - S3-E14
Factual error: When Sam knocks on Diana's door, she opens it. But we've just been told that she's completely deaf, so there's no way she could have heard him knocking. Though she dances to "vibrations in the air," this is with music played at volumes high enough to cause such vibrations. Sam is absolutely not banging on her door that loudly.
