The Poundshop sketch

Man walks into a pound shop, grabs a shop assistant and points to a bowl?

Man: How much is that?
Shop assistant: One pound.
Man: Oh that's too expensive. How much for that one?
SA: That is one pound.
Man: What, is everything one pound in here?
SA: Yes
Man: How about I give you 50 p for that bowl.
SA: No, perhaps you should try the 50p shop down the road.
Man: Why how much would a bowl cost in there?

(Probably needs a bit of work but you get the idea.)
