‘If you don’t mind, we can go under the car and have some fun there,’ the guy says. She agrees but asks, ‘What if they see us under the car?’
‘Then we can tell them that we are checking for a leak in the gas tank,’ the man replies. So they go under the car and have a great time. After a while, a police officer approaches them and yells, ‘What the hell do you think you are doing?’ The couple responds, saying, ‘We are looking for a leak in the gas tank.’ The policeman retorts, ‘You should have checked your brakes first; the car has slid down the slope!
