clownIf the NFL playoff games weren't filled with enough unexpected action to keep you awake this past Sunday, something else was -- a screaming clown.

Walmart aired a new commercial during the games this weekend meant to promote its low prices on party supplies.

Good timing, considering millions of Americans are getting ready to host parties for the Feb. 7 Super Bowl game.

The Walmart ad, which features a misplaced unicorn and a screaming clown, has taken on a life of its own online. It now ranks as the No. 5 on the Viral Video Chart. It's quite a change from a few years ago, when the most action in a Walmart ad was an animated yellow happy face racing around its stores, slashing prices.
