15x30 - Late Show with David Letterman

Two marathon runners interrupt the monologue (one week early, it shall be noted); to honor the possible WGA strike, Bill Scheft chooses not to reveal the punchline to a Dick Cheney joke; Jerry Seinfeld plugs Bee Movie and gets caught in the crosshairs on "Alan Kalter's Celebrity Interview"; Joe Torre dodges questions about his next managerial gig.
