This is from a Walmart "Video Game Challenge" in Porter Ranch, CA today.

Meanwhile, in a North Carolina Walmart, an off-duty rent-a-cop pepper-sprays the shoppers to bring them under control. A fight breaks out at another Walmart over $2 waffle makers, another at one in upstate NY, bringing the current national Black Friday injury total to 24 - and counting.

I find this entire sale ritual so bewildering. "I'm a great parent because I camped out on a sidewalk all night to get you the newest toy at 40 percent off"? My sister and her daughter were out at 4am today - eww. When you could still be warm in bed, sleeping? I don't get it. Is it just me, or is it crazy? Maybe we should be applauding the woman for grabbing a Wall Street-inspired competitive edge!

Authorities are searching for a woman accused of pepper-spraying other shoppers Thursday night at the Walmart in Porter Ranch so that she could grab more discounted merchandise.

Twenty customers, including children, were hurt in the 10:10 p.m. incident, officials said. Shoppers complained of minor skin and eye irritation and sore throats.

"This was customer-versus-customer 'shopping rage,'" said Los Angeles Police Lt. Abel Parga.

The woman used the spray in more than one area of the Walmart "to gain preferred access to a variety of locations in the store," said Los Angeles Fire Capt. James Carson.

"She was competitive shopping," he said.

Black Friday's sales began at the Walmart at 10 p.m. and featured door-buster sales on toys, including $5 Bratz dolls, $10 Wii video games and $29 tricycles.

Meanwhile, two shoppers shot during hold-up attempts at other Walmarts. Beware of Walmarts today!

UPDATE: One grandpa was arrested at a Phoenix Walmart, and a customer was tasered at one in Connecticut.

UPDATE: Another Walmart, more pepper spray.
