TBP sent me this link, courtesy of Good Morning Silicon Valley... John Scalzi's satirical "10 Least Successful Holiday Specials of All Time," as published in National Lampoon. Read his elaborations of:

1. An Algonquin Round Table Christmas (1927)
2. The Mercury Theater of the Air Presents the Assassination of Saint Nicholas (1939)
3. Ayn Rand's A Selfish Christmas (1951)
4. The Lost Star Trek Christmas Episode: "A Most Illogical Holiday" (1968)
5. Bob & Carol & Ted & Santa (1973)
6. A Muppet Christmas with Zbigniew Brzezinski (1978)
7. The Village People in Can't Stop the Christmas Music -- On Ice! (1980)
8. A Canadian Christmas with David Cronenberg (1986)
9. Noam Chomsky: Deconstructing Christmas (1998)
10. Christmas with the Nuge (2002)

My favourite? It was close, but:

"Spurred by the success of The Osbournes on sister network MTV, cable network VH1 contracted zany hard rocker Ted Nugent to help create a "reality" Christmas special. Nugent responded with a special that features the Motor City Madman bowhunting, and then making jerky from, four calling birds, three French hens, two turtle doves, and a partridge in a pear tree, all specially flown in to Nugent's Michigan compound for the occasion...."

Now THAT'S holiday spirit!
