Bottom, Series 3

Richie:
Eddie

Eddie:
Yeah?

Richie:
How do you actually drive a car?

Eddie:
Well, you reach under the dashboard, grab those two wires and jam them together 'til the engine starts up...

Richie:
Uh-huh.

Eddie:
...then, you drink another can of Special Brew, stick a brick on the accelerator and aim it at the post office!

Richie:
Well, I'm just going to turn this key and see what happens...

[Richie starts the car and hits the accelerator pedal, only to reverse through the front window of the local off-licence. Eddie starts grabbing cans of lager off the shelves]

Eddie:
Hey, look, Richie! Special offer!
