Old hat, but if you haven't seen this sequence, it is worth the price of a rental. Cannonballer Adrienne Barbeau gets pulled over after speeding in her Lamborghini, and thinks she's going to ease out of a ticket by giving the cop a downblowse shot. When she looks up after adjusting her cleavage, officer Valerie, not so skimpily endowed herself, grins and says, "Well, I hope you've got a driver's license tucked down in there, somewhere..."
This one IS a classic.
