Kids given vulgar lines in movies?

I was just thinking about this the other night, too, when I rented "Click" and was disgusted to hear swear words coming out of the young children's mouths. It is not funny and not necessary. I'm no prude (f-words fly out of my mouth daily), but there is just no need whatsoever to have children swearing or saying vulgar things in the movies or anywhere, for that matter.
