Not my idea but I wanted to have my own little go at it. Not much time invested and the supposed-to-be-gloves don't really look convincing but I'm quite satisfied with the rest anyway...
Edit:
Wow, thanks to all of you! I really didn't expect such positive response which is why I was kind of surprised today when I found 593 Messages concerning faves and comments in my inbox.
Some have mentioned in the comments he didn't wear gloves in the original picture making it look a little weird in the edited image. So I removed the gloves now.
DETECTIVE SOMERSET: "Did you murder Ronald McDonald?"
JACK NAPIER: "Yeah."
DETECTIVE MILLS: "And why was that Jack? . . . Was it for the money?"
JACK NAPIER: "Hmmmm . . . ha, ha." -soft laughing
DETECTIVE MILLS: "It was wasn't it! You killed McDonald because your Jack In The Box joints were so deep in the hole that you were on the verge of being bankrupt! So you killed him, ya dumped his body in the deep fryer, stoled his identity and his business!"
JACK NAPIER: "WHOOOO! HA HAAAA!" -loud cackling
DETECTIVE SOMERSET: "Whats so funny Jack? . . . "You find murder funny?"
JACK NAPIER: "Ya wanna know why I killed Ronald?" . . . "Hmm?" . . . "It's simple" . . . "He ah, stuck his ah "Big Mac" in Wendy's hot 'n' juicy!" . . ."ha ha"
DETECTIVE MILLS: "He's insane! Look at him, he probably dances around in his grandmothers underware, rubbing himself with peanut butter! Sitting around reading Guns & Ammo, masterbating in your own feces!"
JACK NAPIER: "It's more comfortable for you to lable me as insane."
DETECTIVE MILLS: "It's very comfortable."
JACK NAPIER: "Ah . . . Detective ah, Mills is it? . . . Did you open the box I sent you?"
DETECTIVE MILLS: "What box?
JACK NAPIER: "Heh, I know you got it."
DETECTIVE MILLS: "No I didn't, why? . . . What's in the box?"
JACK NAPIER: "hee hee hee hee." -very softly

JACK NAPIER: "Detective . . . Why so serious?"
As clear as I can see this "Why so Happy Meal" picture in front of me, which is awesome by the way! I could see this being played out on the silver screen. The people who have seen the movie Se7en will understand the inside jokes as well as the Napier name from Tim Burton's "Batman", those who didn't will probably post this sucks! Anyways, I just hope you found it as creative as I found you picture. Hope you enjoyed it and again great job!
