The Young Ones (1982)

Demolition - S1-E1

Revealing mistake: When Rik is watching 'Nozin' Aroun'' on TV, he dislikes the program and smashed the TV with his foot. You can still briefly see the image of the show on the TV, even though the TV is smashed. This means the effects people didn't take the image off the green screen quick enough. Also, a few seconds later when Rik is talking to Mike, there are spikes of the screen remaining around the edge of the TV. However, they are green - the remains of the green screen. (00:27:20)

Boring - S1-E3

Rik: Hey guys, wouldn't it be AMAZING if all this money was real?
Vyvyan: Rik, that is the single most predictable and BORING thing anyone could ever say whilst playing Monopoly.

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.
