"Stephen, you've been taking a lot of shots at my job, I decided I'm going to go ahead and take a shot at yours." 'The Colbert Report' host Stephen Colbert has been teasing his biggest show ever for awhile now, including a stopover in Washington, D.C. and a long-form chat with President Barack Obama, but even he can't possibly have foreseen how that event would turn out. Essentially, it resulted in the talk show host losing his job...to President Obama, who swept on to stage and hijacked the show from an aghast -- but totally willing -- Colbert, only to put his own spin on what it means to host a political chat show. Does Colbert have something to worry about? We vote yes.

"Everybody wants one!" In celebration (maybe?) of this week's long-in-the-making 'Dumb and Dumber,' star Jim Carrey decided to really spice up his appearance last night on 'Jimmy Kimmel Live.' More precisely, he really wanted to Lloyd it up, doling out hideous Lloyd Christmas-styled bowl cuts to the good people of Hollywood Blvd. How could this possibly go wrong?

Here is a brief list of things that happened during Jennifer Lawrence's appearance on 'The Late Show' last night: she sang with host David Letterman, the duo discussed tummy troubles, they chatted about bowling, they both totally biffed introducing a clip, Lawrence begged Letterman to not retire, they walked out during a live taping, and then Lawrence took over the entire show.

For the majority of his appearance on Zach Galifianakis' painful, funny, and painfully funny 'Between Two Ferns,' Brad Pitt seems to be losing out to his host in a big way. At one point, he appears to be trying to hide behind an actual fern. Later, Louis C.K. comes out and stares dismissively at the superstar. Galifianakis calls Pitt's latest film 'Furry.' It's pretty standard 'Ferns' stuff, and Pitt takes it like a champ.

When you've been in Hollywood as long as Michael Keaton has, you've probably seen a lot of weird stuff created by fans -- a lot of signs and strange drawings and maybe a wacky letter here and there -- and although that sounds a little off-putting, Keaton is into it. At least, he's into it when your fan art is good, as was the case with a 'Beetlejuice' tattoo he spotted during a late night shoot on his upcoming 'Birdman.'

Like anyone who lived through the '90s, Jimmy Kimmel loved 'Friends,' but while being a fan of the television staple is wholly understandable, the depth of his affection is, well, perhaps not. Kimmel hosted 'Friends' star Jennifer Aniston on his show last night, and while she might have expected to chat about her latest movie, 'Life of Crime,' and share some fun tidbits and anecdotes, the host had other ideas.

A choked-up Jimmy Fallon took to 'The Tonight Show' last night to pay tribute to the recently passed Robin Williams, a highly emotional affair that should help squeeze one last round of tears out of Williams' many shocked and saddened fans.

During the taping of last night's 'Conan,' the heartbreaking news of Robin Williams' passing was announced. Instead of ignoring the news or saving it for tomorrow or not acknowledging it, host Conan O'Brien took it upon himself to share it with a shocked studio audience, sidekick Andy Richter, and guest Will Arnett. Still stunned and reeling from the news, the trio -- all of whom had worked with Williams in the past -- shared their thoughts on the actor and comedian.

Earlier this month, 'Doctor Who' showrunner Steven Moffat teased a "big introduction" and a "dynamic" hour of television for the series' eighth season premiere, and nothing says "big" and "dynamic" quite like a giant viewing on a massive screen. The BBC has just announced that they are indeed going literal with Moffat's promise: the new season premiere will bow on a big screen near you.

Sure, when you think of actors who have died a lot on screen, there's probably one name that instantly comes to mind: Sean Bean. But don't let the 'Game of Thrones' actor's constant dying-off fool you, there are lots of other actors who bite it all the time. Like Gary Oldman, who is apparently in the top ten of actors who die the most on screen (who exactly is crunching these numbers?).
