Carry On Again Doctor (1969)

Continuity mistake: Gladstone has a drink in Dr Nookey's office, but he doesn't pour it. It just appears in his hand.

Dr. Jimmy Nookey: Hmm. That's a good skeleton. Did the last doctor leave it here?
Gladstone Screwer: That is the last doctor.

Trivia: Jim Dale's final "Carry On" appearance for 23 years before his return in "Carry On Columbus" (1992).
