David Letterman was the guest on Jerry Seinfeld’s internet series Comedians In Cars Getting Coffee this week.

The web-only comedy/interview show always features Jerry Seinfeld inviting a celebrity into a classic car to drive and get coffee.

Letterman’s episode is entitled “I Like Kettlecorn” and is most definitely worth a watch – Dave even dusts off his famous Leno impersonation once or twice.
