A Procter & Gamble Always video, with more than 18 million views in a few days, shows people asked to "act like a girl." Adults and a young boy dance and run with uncoordinated, sloppy moves, but young girls run like, well, normal people.

When asked, "What does it mean to you when I say, 'run like a girl'?" an (adorable) little girl says, "It means run fast as you can." Then the screen reads, "When did doing something 'like a girl' become an insult?"

The campaign encourages girls' confidence:

"Using #LikeAGirl as an insult is a hard knock against any adolescent girl. And since the rest of puberty's really no picnic either, it's easy to see what a huge impact it can have on a girl's self-confidence.

"We're kicking off an epic battle to make sure that girls everywhere keep their confidence throughout puberty and beyond, and making a start by showing them that doing it #LikeAGirl is an awesome thing."

AdAge reports that #LikeAGirl is the second most popular video this week, behind The Last Game, posted by Nike Football, with a remarkable 59 million views.

Discussion Starters:

• The campaign is clearly getting a lot of attention. Why do you think this video is so popular?
• How, if at all, do you think the viral video will translate into sales?
