Here, we're introduced to late night successor to the show. As Gary (aka Craig Eshericks Mustache) described it to us this morning, saying "Bergeron's character was a rather hilarious mashup of Carson (six blonde bombshell ex-wives, elderly white sidekick played by Fred Willard who's been with him for 35 years) and Leno ($80M penalty to cut him loose, because the network wanted to go younger)."

And of course, given David Letterman's scandal, how could they not include a tryst with an Intern?

Like any good crime drama, a gratuitous shirtless scene was included.

Finally, a lead: recordings of the executive talking about contracts and negotiations—and how it'd be nice to get rid of him. After an "intense" interrogation, we discover that the network exec is off the hook—he'd been banging the same actress that Castle had been earlier in the episode (slide #7.)
