shrift in Firefly 2 and the context makes it better... (tiny - not plot spoiling spoiler whited out at end)
Dear Santa,
I hate to say this, but you have to take some of the blame for kids figuring out you're not real. I mean, jolly all the time? Red velvet suit? Lives at the North Pole?
Elves? Dude, we gotta talk about those elves. And Rudolph having a glowing red nose is patently ridiculous, Santa, even you have to admit that.
The flying sleigh is just stupid. Anybody with an Aerospace Engineering degree could tell you just how non-aerodynamic a sleigh is, not to mention the fact that 8 reindeer aren't going to give you enough horsepower to pull a sleigh weighted down with presents for children the world over. Why don't you lay off claiming that magic stuff, too? I mean, it only makes you look silly.
So here's my advice: buy a fleet of Concord jets, subcontract everything (and make sure those contractors sign them forms, yo), and go spend some quality time at your vacation home in the Bahamas with Mrs. Claus.
P.S. I want a Jayne action figure for Christmas, complete with *Vera and a bowie knife accessory. *
