We've just finished watching a Halloween episode where there's a spooking competition to see who can scare the best. At the end, Station Officer Steele scares Norman and wins the competition.
E: That was funny Mummy! I think he won.
Me: Who won what sweetheart?
E: Sir won. He scared Norman!
Me: Do you mean Station Officer Steele?
E: His name is Sir.
Me: I don't think it is sweetie.
E: It is! That's what Sam says!
I can't argue with that, Sam does always call him Sir. It gave me a good chuckle though.
