Robot Chicken, Season 5

Joker:
[laughing sinisterly in his hideout] Watch out, Gotham City, no-one can stop... The Joker! [Batman immediately swoops in, and starts graphically beating up the Joker into submission. A time card then appears reading "Many Hours Later..." and continues to show Batman beating down the Joker. Before he lands another punch, he shakes his wrist out of numbness, then lands the punch, then stops]

Batman:
No! One more punch would kill you! And I won't kill you!

The Joker:
That means somehow I win! I go to jail, break out, kill people, go to jail!! Rinse and repeat -

Batman:
Yes, I know, it's an endless cycle. But I'm sworn to let the courts do their work. [to himself] Now what to do? Hmmm... :[scene immediately cuts to a courtroom]

Judge:
And with the accepted go-to by Batman, [aside glance] thank you, Batman, the court has decided on the death penalty!

Batman:
[to Joker] Sorry, it's out of my hands.

Commissioner Gordon:
Maurice P. Joker, in response to over 200 thousand accounts of murder, and several other crimes that seem minor compared to 200 thousand accounts of murder, you have been sentenced to death. Have you any last words?

The Joker:
[in an almost sincere voice] I knew Jesus has forgiven me.

Police Officer:
Is that a joke?

The Joker:
[sobbing] No! [the police officer then pulls the switch for the electric chair the Joker is strapped to, and he starts to become violently electrocuted]

Police Officer:
That's not right.

Commissioner Gordon:
Keep going until he's dead! It would be monstrous to stop now!!

The Joker:
[as he's still being electrocuted] F*ck you, Dork Knight! [everyone else except for Gordon and Batman throw up in revulsion, soon the Joker shows no sign of movement]

Police Officer:
Oh, oh- [he and a fellow officer investigate the body, and tap it, only to see it react one final time before his head explodes]

Commissioner Gordon:
[nervously backing away] I didn't know- I-I didn't know...

Batman:
Wait! [opens Gordon's palm, to see that one of the shock sponge pads was ripped off the electric chair helmet] But why?

Commissioner Gordon:
[somberly] For Barbara. [Batman grips Gordon, almost threatening to knock him out, until he pulls out the other shock sponge pad. They both laugh it off.]
