How can a mother trying to find the father of her child be offensive?

I found this utube video on Jon Faine's blog this morning, with a warning that some viewers might find the content offensive. Having seen it, I can't imagine WHAT he thought would be offensive. Even if it is a ridiculous hoax, what was bad about it? The idea that a girl might have sex with a boy she just met and likes a lot? The idea that, horror of horrors, she decided not to hide the evidence and have an abortion? Gah.
