Federal officials on Friday unveiled a new 5,000-acre national park where frustrated Americans can blow off some steam by smashing rows of televisions with a bat, screaming at the top of their lungs into a canyon, or playing tracks by Motrhead and the Angry Samoans at extreme volumes. 'I'm as angry as anyone that we can't pass an energy bill or end Don't Ask, Don't Tell,' said Sen. Tom Udall (D-NM), who christened the facility by igniting the contents of a trash barrel, which he then upended and kicked down a rocky slope. 'But in the meantime, the least we can do is give people a place to go where they can just fucking have at it.' Opening day also included an unscheduled appearance by President Obama, who calmly entered the park, let loose a furious stream of undiluted profanity, punched several trees for 55 minutes, and then returned to Washington.
