Character mistake: Cliff tests Norm's memory by asking him who the bad guy in 'Herbie The Love Bug' was (presumably meaning the first movie, which was just 'The Love Bug, ' no Herbie in the title, and not the TV series that actually had the 'Herbie, the Love Bug' title). Norm answers Keenan Wynn, and is told by Cliff that is correct and that his memory is OK. Wynn was the antagonist in the second movie, 'Herbie Rides Again' (reprising his role from the 'Absent-Minded Professor'). The bad guy in 'The Love Bug' was played by David Tomlinson of 'Mary Poppins' fame.
Character mistake: When Sam and Diane are embracing and saying goodbye, Diane asks, "Sam?" and Sam replies, "Yeah, Shel." Shelley is the actor's real name. (00:17:00)
Suggested correction: He says "yeah, chum?" It's another word for pal or friend, which is in line with everything else he has been saying.
