Frankly, it's better than the drugs, violence, smoking, drinking, and profanity that is common in kiddie movies these days. I think they just put that stuff in there to avoid the big G. G and even PG ratings can be the kiss of death at the box office.
Nobody got to excited about Dean Jones' fanny in that first Herbie movie. I remember that he walked all the way across a 70 foot screen in his birthday suit. Or was that some other kiddie movie? I remember being surprised at seeing it in a Disney flick.

I wonder if actors (of both genders) get insulted when the director suggests a body double. "What? Mine isn't good enough!? Are you making fun of my bod?"
