Watch in the scene where Lloyd is driving alongside Mary as she walks through the airport.
He stretches out his hand dramatically to her, and starts to sing, "Good-bye my LOV-"
and he rear-ends a car in front of him. Ha.
His Limo jerks to a stop, and the air-bag inflates in his face. It's very funny. As he tries to push the air-bag out of his face you can see that it is not even attached to the steering wheel. It is just a large balloon that LOOKS like an air-bag. Nice Try. At least they saved money by not actually having to deflate a limosine's air-bag.
