A cop sees this car weaving down the road, so he pulls it over. The cop goes to the driver and asks, "Sir, have you been drinking?"
The driver says, "Sure have. I've had six beers, four shots of tequila, three margaritas, and a whole bottle of vodka."
The cop says, "Sir, I'll need to give you a breathalyzer test."
And the driver yells, "What, you don't believe me?"
