FX SHOP DOOR OPENING
Jeremy: Cars! Cars! Cars!
Mike: Yes. How can I help you sir?
Jeremy: How can you help me? By shutting up! (SNORTS) You see I'm a man who answers his own questions. A man who decides what to wear a year in adavance. That's the kind of guy I am. Unique. Special (BEAT) And I've come shopping!
Sue: (SIGHS) Jeremy? Will you please stop talking like that? You're not even on camera. I'm awfully sorry.
Mike: No...
Jeremy: How about I do the talking? Yes. OK. 0 - 60 in the time it takes to tie my laces? A paint job so good I can see my dead grandmothers face in the bonnet? Wheels so round I could say the word 'marmalade' at least twice a day? Can it do these things?
Mike: Erm... I... All I know is (BEAT) it comes with batteries.
Ellie (AGE 6): Mum? Can we go home? I don't want a remote control car anymore.
Sue: We'll be waiting in the car!
Jeremy: And that's why Jesus...
Mike: Can you leave the store please sir?
Jeremy: You... I mean look.... Cars! Cars! Cars!
