You Gotta Lose This Job - S3-E7
Visible crew/equipment: When 'Hannah' and Lilly walk into Rob Reiner's office, the multiple head studio lights are reflected on Hannah's large black sunglasses.
Revealing mistake: In the opening credits, Beefy Bert has a different hair colour to what he has in the actual episodes. This was not included in Series 3.
Continuity mistake: When Lewis tells Rikki about Dr. Denman, he's pointing at her in the close-up but not in the wide shot. (00:01:50)
