Only Fools and Horses (1981)

The Long Legs of the Law - S2-E1

Revealing mistake: At the very beginning of the episode, Leonard Pearce is waiting for the cue for his character to start looking for his teeth. He's standing in the living room, between his room and Del and Rodney's room. (00:00:25)

Modern Men - S8-E2

Uncle Albert: Is that the radio I hear, Rodney?
Rodney: No, Elton John popped in and he's rehearsing in the kitchen!

Trivia: The story behind why Trigger calls Rodney Dave is that apparently Roger Lloyd Pack kept getting names mixed up during rehearsals early on in the show's history. "Dave" came from David Jason when he was actually with Nicholas Lyndhurst [Rodney]. It stuck and quickly became part of the show's immense appeal.
