I realize I'm a little late to this party, but I finally dove into Comedians In Cars Getting Coffee by Jerry Seinfeld. It's very funny.
Almost all episodes run less than 20 minutes each so you can bang off a season fairly quickly. Guests include such funny people as Larry David, Ricky Gervais, Louis C.K., Sarah Silverman, David Letterman, and Chris Rock.
And best of all, all episodes are available online at http://comediansincarsgettingcoffee.com/. This is the podcast of television shows!
