Don't you mean you need a leg?

The other day i missed Neighbours. And i missed the best scene in Australian TV of recent history:
Paul Robinson, who recently had his leg amputated due to medical complications, is struggling with something. Izzy, who currently lives with him in his lair/house is just sitting around or whatever, ignoring him.

Paul: "Uh, i need a hand here!"

Izzy: "Don't you mean you need a leg, Paul?"
