The first one is a stereotype!  It's NOT funny!
And that can also hurt people's feelings!

Well, since it's done in a humorous tone I don't really see how it's offensive. Parodies about stereotypes just kind of enforces you to laugh at them because they're so ridiculous. Not sure if this was the case, but I'm sure people will see it that way.

PS. I like the color pink and I love the Barbie Girl song. (That song isn't even supposed to be girly, it's actually a really dirty song meant to be funny.) I just like to rebel against the common stereotype for the color pink. Yes it mostly represents femininity, but that doesn't mean the feminine person who likes it is a girly girl. I love pink and I also love to watch monster truck shows while shouting "YEEEEAAAAAAA" with my guy friends. (I wore a bright pink shirt with white stripes to one of those shows once, haha, I looked so out of place.)

Regardless, I didn't find those bloopers funny, they're just a bunch of nonsense. And the quality of the video was really hurting my eyes. :[

The frequent use of potty talk (I haven't heard that since I was 6) really stuck out as the only way the author could think of to be funny.
