A policeman sees a car weaving all over the road and hits his flashing lights.
He walks up to the driver's window and sees a good looking woman behind the wheel.
There is a strong smell liquor on her breath.
He says, "I'm going to give you a breathalyzer test to determine if you are under the influence of alcohol."
She blows up the balloon and he walks it back to his patrol unit.
After a couple of minutes, he returns to her car and says,
"It looks like you've had a couple of stiff ones."
She replies, "You mean it shows that, too?"
