LUCASFILM: 2000
Rick: Hey Georgie, we’re filming in a few days. How goes the script writing?
George: Oh, well gee golly, I haven’t written it ye-- I MEAN not the final draft since I wrote it back in 1975 with the rest, of course.
RM: Are you okay, daddy?
GL: Fine, honey, I’m fine. Anyway, uh, just go on to the set and I’ll meet you there.
Exit Rick
GL: Okay, um, okay…

GL: Haha! I’m a genius.
GL powers up his computer, ready to type his magnum opus.
