This is an idea I've had buzzing round in my head for a while, so I decided to have a go at finishing it.
Int. Car
3 men in balaclavas are in the car: Simon is sat in the passenger seat, Terry in the back and Gavin is sat at the wheel with the motor running. Simon and Terry have shotguns.
Simon: Now, we're clear on the plan aren't we?
Terry/Gavin: Yes.
Simon: Right, let's go.
Gavin goes to get out of the car.
Simon: What are you doing?
Gavin: We're gonna rob the bank.
Simon: You're the getaway driver! You stay here!
Terry: I thought I was the driver.
Simon: Of course you're not! Why d'you think you're in the back?!
Terry: Because he (POINTS AT GAVIN) gets carsick in the back.
Simon: GOD NO!
Terry: He does get carsick!
Gavin: I do, y'know.
Simon: Look, you're the driver and you're coming with me!
Terry: What are you getting so worked up for?
Simon: Because I've been planning this for months. We can't mess it up. Now, are we ready?
Terry/Gavin: Yes.
Simon: Right, let's go.
They burst out of the car leaving Gavin at the wheel. A few seconds pass. Simon and Terry get back in the car.
Gavin: That was quick.
Terry: Bank holiday.
Simon: Can we just go please.
