Box Office Challenge: 'Chihuahua' barks up a win

Woof woof woof! That, dear friends, is this week’s signature cry of victory, after Beverly Hills Chihuahua barked up a big win at the multiplex. And, with about 60 percent of players in EW.com’s Fall Box Office Challenge picking the little mutt to be the movies’ top dog, similar bellows could be heard throughout cyberspace, no doubt. (A big bark-out goes to “Chrisclb120” for winning the frame.)
