This is going to be a fascinating three parter - did they talk to CBS before writing this? Did they talk to Letterman?
I love the fantasy casting element - who would you pick to replace Letterman when he retires? Seinfeld would actually be pretty awesome, as his new web series - "Comedians in Cars Getting Coffee" has revealed (search it on tv.com, the Larry David pilot is especially worth the watch). Can't wait to see where they take it.
