It would be a great show if MTV didn't glorify their idiocy and bad choices so much. I think it's good for the public to know that not only comfortably married people have children, and it's an eye opener for those that think this way.
However, it's sad because though they've decided to accept the responsibility of a child, they still act like complete dumb asses. MTV seems to pick the cream of the crop- I know that not all teenage parents act like that. There are those that ACTUALLY step up to the plate and do their best to be good parents, despite their situation.
