Revealing mistake: The guy who plays Clive in this episode has one of the most appalling accents I have heard. He's apparently from Manchester, but sounds like a sort of cockney South African. His accent slips around all the time; it's very poor. I wouldn't normally submit it, but his is so shockingly bad I doubt anyone would be fooled into thinking he was British.David Mercier
Factual error: At the cafe, the employee says that Niles' credit card was declined at the register because "cancelled by order of co-signatory." A co-signatory shouldn't be able to cancel the card without the other person.
