In the scene where Wayne and Garth are sitting on the car by the airport, the were talking waiting for the planes to fly over. They started the scene and got through the dialogue right before when the plane was suppose to come. Only the plane was a little bit late. Spontaneously, Dana Carvey (Garth) asked Wayne if he found Bugs Bunny attractive when he put on a dress and played girl bunny. This was not in the script. You can tell by Wayne's laugh that it wasn't expected. Just then the plane came and the director decided to keep the line in the movie
