Perhaps taking a cue from old pal Regis Philbin, David Letterman casually mentioned during last night’s Late Show that he only plans on sticking around for another two years. The moment came during a talk with Howard Stern, where the radio host took the opportunity to once again wax rhapsodic on his fervent hatred for Jay Leno, and then later follow it up with a story about his recent contract battle and his chess-filled retirement fantasies. You can see for yourself in the below video around the 2:40 mark, where Stern asks Letterman how much longer he plans to stick around, to which Letterman replies, “I don’t know. Maybe two more years?”
