'Downton Abbey' Season 3 alternate ending courtesy of Conan O'Brien

By now, you've probably heard that "Downton Abbey" sent fans reeling when it killed off Matthew Crawley at the end of the third season in an automobile accident. But TBS late-night host Conan O'Brien has a better idea of how it could have ended.

GIANT MAN-EATING SNAKE! It's certainly a more exciting end than a silly car crash.

Heh. O'Brien dubs it, "Best episode they've ever had."
