*The premise is that the viewer is seeing Bugs Bunny at the start of his career, working as an extra on the set of a musical;
Move down from cartoon sky-writing saying 'Coke' to a cutesy cartoon chorus of little birds, fawns, squirrels, etc. all singing a saccharine Disney-type song. We see in amongst the extras the bored figure of Bugs Bunny.
The cartoon director yells 'Cut' and the chorus take a break.
They gather together on the set.
A squirrel comes up to Bugs.
Squirrel: Hey, nice scampering Bugs.
A fawn pats him on the back
Fawn: Yeah like an old pro.
Squirrel: This is my tenth picture as an extra. Great bunch of guys.
The squirrel points out the other animals who have started up a game of cards (NOT POKER)
Fawn: You ought to stick around. You could carve yourself out quite a niche with those cute, floppy ears.
Bugs Bunny scowls and takes a swig of Coke. An owl hops over.
Owl: Hey, you drinking Coke? We guys don't drink Coke since they changed it. We like the same old routines.
Gopher: We're old pros and we stand by the status quos.
Bugs shrugs off their bonhomie
Bugs: Aw can it. I'm off. I've had it with you stick-in-the-muds. I'm gonna have my name in lights, my own series...
An irate duck waddles over, jumping up and down in excitement .
Duck: Nobody who drinks that new Coke's ever gonna amount to no hill o' beans.
Bugs cooly turns to the angry duck.
Bugs: (Nearly uttering his immortal line for the first time.) "What's up, Duck?"
The director walks over suddenly interested, as if spotting a star.
Director: "Hey Wabbit, say dat again."
SUPER: "COKE. YOU GOTTA MOVE ON."
