"V-Day" -- by Leo Burnett/Chicago for Tampax

"V-Day" kicks off a new online video effort by Tampax that follows the story of Zack Johnson, a guy who woke up one morning to find he has a gaping vagina where his second head should be.

Don't know how it'll all pan out, but it promises to be occasionally funny in a banal teen angst kind of way. Follow the progression at Zack16.com, a site reminiscent of a teenage boy's notebook, complete with videos, a blog, Polaroid-styled images and a Twitter feed.

The tweets are kind of funny and appear to be getting progressively more emo. Apparently he's already had a period and now feels every guy should experience one.

Hear, hear. Although to be frank, marvelous breakthroughs in birth control make it so even real women don't have to endure random visits from Aunt Flo anymore.
