Bottom (1991)

Dough - S3-E4

Continuity mistake: When Ritchie, Eddie, Spudgun and Dave Hedgehog enter the pub with the fake money and order drinks, Ritchie asks for Absinthe but is told that the pub doesn't have any and is given Pernod instead. Later, when the £5000 pub quiz poster is pointed out, Ritchie says he's had half a pint of Absinthe and can't see anything. Where did the Absinthe come from if the pub didn't have any earlier in the episode and they never left?

Revealing mistake: Just before Richie gets his crotch set on fire by Eddie, you can see the flammable substance already smeared on his trousers.

Visible crew/equipment: When Dick Head the barman is explaining to Richie, Eddie and friends that Skullcrusher Henderson is going to be visiting them to "discuss" their counterfeiting operation, a huge boom shadow crosses the scene back and forth several times.
