Comedian Bill Hader has been on 'Saturday Night Live' (Sat., 11:30PM ET on NBC) for many years now. He's also starred in such movies as 'Superbad' and 'Forgetting Sarah Marshall.' But even for an experienced comedian, performing on live TV can be tough. And unexpected problems occurred on the latest episode of 'SNL' when Hader started struggling with his lines.

Ryan Phillippe is perhaps best known for being the ex-husband of actress Reese Witherspoon. But now, maybe he'll be known for donning a skintight unitard on 'Saturday Night Live' (Sat., 11:30PM ET on NBC).

Comedienne Tina Fey does such an excellent job of parodying Sarah Palin that sometimes, it's tough to tell the difference between them. On the latest episode of 'Saturday Night Live' (Sat., 11:30PM ET on NBC), Fey announced the creation of the fictional "Sarah Palin Network." And one of the new shows on the fictional network was: "Hey Journalist, I Gotcha!" In the show, Palin/Fey strikes back against the journalists who roasted her during the 2008 presidential campaign.

Tina Fey's surprise return to Saturday Night Live as Sarah Palin was one of the ten greatest TV moments of 2008 (and quite possibly the decade, the century, the millennium and the eon).

So it's no surprise that Fey's name and show 30 Rock came up so many times in the recent list of Emmy nods. I'm no longer convinced that she's a woman. I'm convinced she's an experimental humanoid prototype designed by studio executives solely to win awards like Tom Hanks (aka "Project Red Shoe").

It's also no surprise that one of the two acting nods she scored included her Palin performance on SNL.

Christmas is the easiest holiday to make fun of because it can be so hokey and jolly. It's like the office jolly holly -- someone who's always smiling, always bringing gooey sweet goodies to the office for no reason, always cackling at everyone's jokes, no matter how bad they are or what MadTV episode they were taken from.

But deep down, you know that anyone that happy has to be making up for something equivalently dark and sinister. They are hiding a dark secret, something they can't even admit to themselves. You just know that the rises in sick leave usage after she brings her secret recipe brownies aren't coincidences.

Christmas wears the same mask. All it takes is a little scratching to find something dark and funny behind its red and white veneer. SNL has had some great success taking pot shots at Christmas, even during the down times, for this very reason. It's hard not to find something funny about Christmas, but it's hard to keep finding something funny about it long after the turkey has been picked clean and the eggnog has left a thin layer of plaque on the inside of your small intestine. Here are the best of the best.
