As we noted yesterday, Kristin Cavallari recently attempted to count down from 10 and failed. On Wednesday, she began a 10-day countdown on Instagram in order to give away signed copies of her forthcoming book Balancing in Heels. “Doing 10 days of signed giveaways for #BalancingInHeels!” she wrote. “Like this picture to enter to win a signed book. My publisher @rodalebooks will direct message the winner each day [confetti emoji].”

Former Laguna Beach star Kristin Cavallari began a 10-day countdown on Instagram this week.

Like this picture to enter to win a signed book. My publisher @rodalebooks will direct message the winner each day [confetti emoji].”

So people estimated that a $3 item marked down to $2.22 was actually more expensive than a $3 item marked down to $2.33.

If only it were as simple to count everyone in America as "One, two... three hundred million." Nope. It's still about four months away, but the 2010 Census is already under attack by people wracked with existential angst.
