After 15 years on the fringes of Pakistani national politics, Imran Khan is now at the epicenter.

He first rose to prominence decades ago as the rakish star of Pakistan's cricket team, the country's national passion. He's now trying to reshape Pakistan's political game, outmaneuvering old-time political pros with his Tareek-e-Insaf (Justice Party).

The supercommittee's failure puts in motion automatic budget cuts for the Pentagon of $600 billion — a process called sequestration. On Monday, even before the supercommittee flamed out, defense workers in York, Pa., rallied to protect the Pentagon budget and perhaps their own jobs.

The local congressman, Republican Todd Platts, spoke to the workers and said that Republicans and Democrats in Congress should also do their work as Americans.

Phones today beep and buzz. MP3s don't scratch. Noises that were once familiar, such as the clacking of manual typewriter keys or the ding of the gas station driveway bell, have all but vanished. Kara Kovalchik of MentalFloss.com shares these and other sounds your kids have probably never heard.

She commands any space, especially from behind a set-up of a tom and snare drum, a ukulele, and her bare feet atop the loop pedals from which she builds her compositions.

Nicholas Stoller made his directorial debut with 2008's raunchy comedy Forgetting Sarah Marshall, which starred Jason Segel as a guy who had to reassess his life after his girlfriend of five years dumped him.
