Bottom's Up - S1-E5
Continuity mistake: When Eddie goes down to fight the looters the sky is totally blue. But all of 2 minutes later when he comes back on the roof, the sky is totally grey. Not a chance could that happen so quickly.
Revealing mistake: When they are leading Richie to the cupboard while playing postman's knock, Dave Hedgehog puts his hands on the wall. The whole stage wall shakes when he touches it.
Visible crew/equipment: Whilst Eddie is watching Miss World on the television, Richie walks over to the window to clear the uneaten food from the plates. In the shot shown from the window looking into the apartment, just as the shot starts, a boom mic can be seen towards the left of shot and is then quickly pulled out of frame. (00:13:55)
