According to reports, David Letterman is paying his entire writing staff's wages - out of his own money - through the end of the 2007 calendar year.
A number of tv stars have publicly stated their support for the striking writers; Eva Longoria and Jay Leno are two of the most notable. And, to be honest, that's pretty admirable of them - after all, siding with the writers means siding against the people who pay them millions of dollars a year. Having said that, Leno supported the striking writers by bringing a group of striking writers coffee and doughnuts on his Harley, while Letterman is paying them a lot of money out of his own pocket. Regardless of whether you think he's funny - and I'll be the first person to admit that his show has slipped in recent years - Letterman is still one heck of a cool, likable guy, and his quiet dignity stands in stark contrast to, well, just about everybody else associated with the television industry.
(Reason #1, of course, is that he's much, much funnier than Leno, but you already knew that.)
