If there's two things America loves, it's high school and musicals. Okay, not everyone loves high school -- social outcasts, I'm looking at you -- but most young kids can't wait to get there, and most adults wish they could relive it. So it's no wonder that High School Musical 3: Senior Year remains at the top of the U.S. box office for the second week in a row, bringing in another $15 million for a total of $61.7 million. In other frightening -in-a-wholly-expected-way Halloween news, Beverly Hills Chihuahua made another $4.7 million and is still at #6, for a total of $84 million. Because if there's three additional things Americans love, it's dogs, Mexico and rich people.
