I've got a story going where the MCs are dressing up as the Joker and Harley for a Halloween party. They're trying to win a contest, and both do good impressions of the characters, on top of having crafted excellent costumes. It's their ace in the hole that they think will make them stand out.
I don't use many of them, but I am using a few lines that are direct quotes from across the Joker canon. "Wait 'til they get a load of me" from '89, "Why so serious?" from Dark Knight. I'm also using some paraphrasing of lines such as "You put the fun in funeral" from Harley. The first two are actually attributed in the narrative, because it fits into the story. He's dressed as BTAS Joker, doing the Hamill voice, and borrowing lines from other Jokers for his impression. If I have him doing any Hamill lines, there's no logical reason to attribute them in the narrative beyond pure nerdosity of quoting episode numbers or titles, which I don't feel like fits the character.
As to the emulation, that's the nicknames, which are used far more frequently. Mr. J, Puddin', Pumpkin Pie. and the general not ha-ha funny, more stab-stab funny style of the dialogue of the characters.
( That last description is itself a quote paraphrase from the Arkham Redemption sketch on Robot Chicken. See why I say there's little doubt I've done it before? )
Figured I'd ask in advance, so I know if I can post this one here. ( 'Cause I ain't changin' it
That's provided I actually finish the damn thing this year. I plotted it out two years ago. Wrote the opening scene last year, and finally got to the part I'm asking about this year.
