I always love the part of this episode that sadly, was never animated and thus never aired. But Paul Dini told the story of it in this episode's commentary.
Basically, Batman's walking back to the Batmobile with Pig Wonder Woman. Then it cuts to a shot of Joker in a van outside a bank, with his gang and Harley. They're all set to go break in when Bats walks by, craddling Wonder Pig, saying "it's all right, everything will be okay."
Joker pauses with a WTF face and then says, "That's IT! Everybody pack up! We're leaving!" Harley: "But Mr. J!" "Nope, nope, nope! We're out! I can't top that!"
