James Buckley who plays Jay actually has both of his ears pierced, not just one, like is seen in this episode.
In the episode, Simon's Mum is only seen behind either people or props and her body isn't seen throughout the episode. This is because she was heavily pregnant when this episode was filmed.
Mr Gilbert: Cartwright, what is that in your ear?
Jay: It's a stud sir, and I don't mean the earring.
Simon: Hang on, have you had the left ear pierced?
Simon: Aint that the one you get pierced to show you're gay?
Jay: FUCK OFF!
Neil: Oh yeah that is the gay one.
Jay: Well there's a quick way to tell Neil, which ear's your dad got pierced?
Neil: Neither cos he's not bent!
Simon: Course not.
Jay: Morning Benders, jump in the minge mobile.
Will: Strange thing to call your mums car.
Jay: Oh well done you've mastered walking like a knob and looking like a dick at the same time.
Simon: This is actually enjoyable, in a 'I'm shitting myself' kind of way.
Neil: If you've shit yourself in them trousers I aint touching them.
Simon: Of course I haven't.
Neil: You walk like you have.
Jay: Alright gays?
Neil: How's your ear Jay?
Jay: Perfect, that's why I've got to wear this massive bandage.
Neil: Oh, I suppose that's your modelling career fucked then.
Will: He never had a modelling career!
Jay: Yeah but I'm not bothered, cos I fucked the nurse that looked after me.
Will: The St. Johns Ambulance lady?
Simon: Isn't she Warren Duncan's nan?
Jay: No there was another one who looked like Lucy Pinder.
Will: Course there was.
In the first scene where Jay is driving, his hair is longer than it is in the next scene when the lads are in the common room, when Gilbert is talking to them.
