Watch: Jimmy Fallon parodies "Breaking Bad"

He is the one who knocks (if you're looking for knock-knock jokes).

In the fashion of "Game of Desks" and "Downton Sixbey," Jimmy Fallon has delivered another spot-on TV parody -- this time, for "Breaking Bad."

On Wednesday, the "Late Night" host debuted "Joking Bad," a 13 (yes, 13)-minute-long spoof with him as the bald, bespectacled joke kingpin, "Fallsonberg."

The parody is packed with star cameos -- look out for Bryan Cranston, Aaron Paul, Bob Odenkirk (who will star in the spin-off "Better Call Saul") and a certain departing "Tonight Show" host.

Watch the whole thing below (but take note -- there is some language in the clip, but nothing you haven't heard Jesse Pinkman say many times before):
