- Cashier: Sorry to have kept you, what can I get you?
- Dave Briggs: Erm, I'll have six of these please.
- [Briggs puts six cans of lager on the counter]
- Cashier: Oh, you do know that with every three you buy of those, you get one free?
- Dave Briggs: Really?
- Bob Louis: So, we've got six, but we get two more free?
- Cashier: That's right.
- Dave Briggs: Go on then, Bob.
- [Louis puts two more cans on the counter]
- Bob Louis: Hang on Dave. We've got eight cans, right?
- Dave Briggs: Yeah.
- Bob Louis: If we buy another one, we can get three free.
- Dave Briggs: That's true.
- [Louis puts four more cans on the counter]
- Dave Briggs: Erm, we'll have nine cans please, miss.
- Bob Louis: And these three are free.
- Bob Louis: Great this, innit?
- Dave Briggs: Hang on, we've got twelve cans, right? Well threes into twelve goes four. We should have four free ones.
- Cashier: So, you want to pay for twelve, and have four free?
- Bob Louis: Well, if they're free, yeah.
- [Briggs puts four more cans on the counter]
- Dave Briggs: [Briggs pulls Louis off to the side and asks quietly] How many do you make it now?
- Bob Louis: Sixteen.
- Dave Briggs: If we buy two more, we get six free ones.
- Bob Louis: We only came in for six.
- Dave Briggs: We've got 'em for nothing.
- Bob Louis: Hey, with the money we've saved, we can buy six more.
- Dave Briggs: Blimey, you're a genius... Excuse me miss.
- [Louis puts six more cans on the counter]
- Bob Louis: [after leaving the store] Dave, what I can't work out is if we've just saved so much money, why is it I've only got 78 pence to see me through the rest of Christmas?
- Dave Briggs: It's called Supply Side Economics, trickle down, it's all to do with the EMU.
- Bob Louis: Still, it is Christmas.
- Dave Briggs: Yeah. Hey, and what do you need money for anyway? We've got everything we need for the next week here in our hands.
- Bob Louis: Bird with one leg, seventy six cans of lager.
- Dave Briggs: All I need now to make my Christmas complete, would be World Peace, and an electric screwdriver.
