I saw a clip from the Young Justice episode. I didn't see the Injustice League really take over television but what I did see Joker using was close enough. Theblank can have it.

The other instance I was thinking of, other than the Joker in the Justice League series, was Control Freak on Teen Titans, who pretty much did the same thing the Joker did to the Justice League, except to Titans East.
