Jimmy Fallon did a parody of Breaking Bad titled Joking Bad -- featuring cameos by  Bryan Cranston, Aaron Paul, Jey Leno and Bob Odenkirk -- on his late night show Wednesday.

Fallon closed his show with a sketch about "joking bad" in which he posed as Walter White and Steve Higgins played Jesse Pinkman. The sketch started with Fallon receiving bad news from the top boss about being dropped from the Late Night Show and how he had only six months to wrap up, though he did assure him about his new gig at The Tonight Show. Fallon will be taking the reigns from Jay Leno, who will be hosting his last show on Feb. 6, 2014.

Jay Leno talks about plans after leaving The Tonight Show with Craig Ferguson.

In the next scene, Fallon was metamorphosed into a Walter look-alike. He bumped into Higgins in the ghetto neighborhood where the latter was hustling bad jokes. Fallon was impressed by the money Higgins was making for the terrible jokes and chose to team up with him. The two started brainstorming in a building that was being fumigated. They cracked equations and built formulaes like "Anthony Weiner + One Direction = One Erection." Once they got done with all the hard work, Jesse tried to sell the goods outside the Comedy Cellar and found his first customer.

The head writer of the Late Night Show was the Hank Schrader of this lot, he picked up on Fallon's deceitful practices and started investigating him. Bob Odenkirk played his Breaking Bad character Saul, who is Fallon's agent in the parody.

Having sold all the jokes, Fallon ran out of material for the Late Night Show and ended up bumbling through his monologue as a disappointed audience looked on. The crowd included Bryan Cranston -- who showed his disgust by flinging a pizza on stage -- and Aaron Paul, who leaded the booing against Fallon.

The sketch closed with a guest appearance by Leno. The Tonight Show host parodied Hector Salamanca, the paralyzed and mute uncle of Tuco Salamanca who conveyed his messages via a brass service bell. When asked if Leno wants Fallon dead, Leno rang bell loud and clear.
