The Young Ones (1982)

Oil - S1-E2

Visible crew/equipment: When Vyvyan tells Neil he has 3 seconds to make supper, a boom mic shadow can be seen on the far right side of the screen on the cupboard. (00:10:30)

Dwarf

Summer Holiday - S2-E6

Mike: Where's Vyvyan?
Rik: Well, he said he was going inside to water his plant. Strange that such a ruthless and sadistic maniac as Vyvyan should care for a begonia. Must have had it two years now.
Mike: And it was dead when he got it.
Rik: Yes... Still, give him his credit - he's watered it every day!
Mike: Only because he can't be bothered to go upstairs to the lavatory.

Bambi - S2-E1

Trivia: It's obvious that they just walked into the train station and started filming, because all throughout the sequence people are staring at them.

Boring - S1-E3

Question: What is the name of the band playing in the pub? They sing 'Welcome to the House of Fun' and seem very familiar to me, but I can't figure out how.
