Dark days on the beat got you down? Mucked up that whole warrant thing again? Sad because your wife is too hot for you? Upset that you sold your baby on the black market? Try bursting into song! Guest star Kelley returns for a very special musical series with plenty to talk about, if Jon would ever shut up about his breakdancing skills.

RoboCop, Joe Cocker, Glen, Sheryl Crow’s trailer, and ponytail Steve Zahn are also discussed.
