Scripts aren't necessary, but when they are necessary for something hilarious dreamed up by their dad, or dad's best friend, or, what the hell, a major advertising campaign, it's the furthest thing from “work” I could ever imagine. One of my favorites is "Bat-Dad" or something like that. The father dons a Batman mask and holds the camera at an angle so that you can see the background as well as his face (in the corner of the screen). Then he talks deep and raspy, like the recent "Dark Knight" Batman does. He scares the bejeezus out of his wife by yelling at her in his Batman voice and she always jumps -- but that's not the funny part. One time, he addressed his young son who was riding in the back seat of the car by yelling at the top of his Batman lungs:
Where is she?!?!?!I don't want to ruin the moment, it was a little bit scary to watch (Dark Knight was meant to be a scarier version of Batman, and this phrase was intonated just as if it came straight out of a tense scene in one of the later movies), but the young son seemed to handle it well. You are going to have to watch what happens next ... I will not spill the beans!
