This has to be one of the best advertising campaigns I've seen in some time. A teen girl wanted to fit in so bad, she faked her first period. 'I tried everything to get my period. Nothing. So I faked it.' Her friends bought it, but her mother didn't.

When mom asked her daughter what the pad with red nail polish was she replied, 'What do you think it is. I'm on my ladies days.'

What does mom think it is? 'Rubylishish nailpolish. But she doesn't need to know that.'

'We have to celebrate. It's family tradition. We're throwing you a first moon party,' mom tells her daughter, because 'It's one thing to lie to me, but to take that tone, it's on.'

Mom calls in the grandparents, her friends and even her 'friggin' co-workers to celebrate with pin the pad on the period, a vagina cake, a uterus pinata, a vagician and grandpa bobbing for ovaries.

Finally the girl cracks, telling her mom she faked it. That's when mom hands over the period starter kit. 'Aren't you going to ground me for lying,' her daughter asks. 'Why do you think I threw you the first moon party,' mom tells her.

How did mom know? 'Periods don't have glitter in them.'

Kids don't realize, moms know EVERYTHING and we're the best at teaching our kids a lesson they won't soon forget, especially when they lie.
