Revealing: During a few scenes after Richie's finger has been taped back on at an extreme angle, you can see Rick Mayall's real finger bent underneath it. This is most visible after his finger gets slammed in the window: look carefully after the window is opened.

Visible crew/equipment: At the start of the episode when Eddie and Richie get home, a yellow boom mic can be seen above their heads.

Continuity: When Richie is telling the other 3 guys to go to the corner, he still has his hands on the wheels of his chair. But when the shot changes and Richie says "if you need the toilet then put your hand up", his arms are crossed around his waist.

Continuity: When Richie and Eddie are on the roof and Richie starts his rain dance, watch the bottom of his trousers. To start of with he pulls the hem up to around his shins. He then starts and pulls his groin or something and stops and at this point the right hand trouser falls back down his leg. Then straight afterwards in the long shot you can see that it's back up again without him pulling it up.

Continuity: Eddie says that the fairground music reminded him of his dads funeral. But in many of the other episodes Eddie says that he has no idea who his father was.

Revealing: When Eddie ties the string to Richie's leg and slams the door, watch the leg. The jeans actually rip and the fake leg comes out and you can even see the actor's real leg tied underneath. It's really obvious in slow motion.
