This is a misleading and frankly a pretty insulting headline. Quoting a comment from the original article:

"Okay, so really what the study is saying is that women EXERCISE less than men, not that they are lazier. They are probably too busy working - earning money, performing childcare, managing the home, and a myriad of other things - to get the kind of exercise that might show up in this study. Check out http://www.economist.com/node/13717514 to see data from 18 OECD countries showing that men have more leisure time than women."

Uh... you should check out his other Charlie videos. This guy is a huge, abusive prick. Not to echo the people that claim every animal video on youtube is animal abuse, but this actually is. He even comments that he doesn't give a fuck about the duck and doesn't have "emotional attachment".

Wait, which one is supposed to be the fat one? I don't see these women deviating much from the typical Hollywood "look". Funny how just 20 extra pounds or a non-typical face in Hollywood is considered some sort of bold or radical statement against the Hollywood "It" body. You'd never think Lena was "fat" if you saw her on the subway with everyone else.
