Jimmy Kimmel

Joaquin Phoenix knows a pullout couch when he sees one -- even if its own owner isn't aware of its convenient (and comfy!) extras. On last night's 'Jimmy Kimmel Live,' guest Joaquin Phoenix somehow hit upon the idea that he and host Jimmy Kimmel should pop into bed to close out the show. Where do ideas come from? What day is it? Where will someone find a bed on the stage of a late night talk show?

The demands of filming a television series -- especially a highly anticipated one like Marvel's own 'Agent Carter' -- often lead to some strange side effects that bleed over into real life. For star Hayley Atwell (the eponymous Agent Peggy Carter herself), that apparently included having to run errands while done up in full post-World War II regalia.

For his latest round of "Celebrities Read Mean Tweets," Jimmy Kimmel trotted out his most star-studded line-up of celebs yet, including Gwyneth Paltrow, Lena Dunham, Gerard Butler, Ty Burrell, Bob Newhart, Britney Spears, Geena Davis, Chris Pratt, Chloe Grace Moretz, Scott Foley, Michael Chiklis, Ted Danson (Ted Danson? who tweets mean things about Ted Danson?), John Stamos, Lisa Kudrow, and Adam Sandler. But he also rounded up the meanest collection of, well, #meantweets ever. These tweets are really mean, you guys!

"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?

Christoph Waltz would like you to believe that he's always starred in darker, more dramatic fare. Christoph Waltz would like his fans to think of him as a two-time Oscar-winning actor. Christoph Waltz has some secrets.

Starting off in Hollywood is rarely a glamorous endeavor -- rather, it's one the requires hard work, patience, and a handful of really bad side gigs meant to supplement a budding star's cash flow until they hit the big time. Melissa McCarthy might be one of our biggest stars, but McCarthy definitely paid her dues before rocketing to the star stratosphere.

For the better part of 2014, Shia LaBeouf's antics were the talk of the gossip world. Can we even call them just "antics"? There was an arrest and an art installation, after all. Things were just weird, okay? The actor seems to have recovered from whatever was addling him, and he recently hit the talk show circuit in support of his upcoming World War II film, 'Fury,' a tour that inevitably results in his having to talk about, well, everything.

Beloved (but also maligned) series 'LOST' turned 10 last night -- in TV time, that means last night marked with 10th anniversary of its very first show -- and Jimmy Kimmel took the opportunity to check in with one of the show's original stars: Walt!

Marvel has been making some big changes to its standard comic book lore lately -- introducing both a new female Thor and a new black Captain America over the course of mere days -- and rival comic book giant DC does not want to be left behind. DC is progressive, too, you guys, and what better time to unveil their new take on a beloved superheroine than during Comic-Con week? It just makes sense!

The World’s Ugliest Dog Contest was held over the weekend as part of the Sonoma-Marin Fair in Petaluma, California. The contest pits the world’s biggest canine eyesores against one another. This year’s winner is Peanut, a former shelter dog from Greenville, North Carolina.

Jason Momoa is tight-lipped. Sure, the former 'Game of Thrones' and future 'Batman v Superman' star is happy to be on 'Jimmy Kimmel Live' to chat it up with professed big fan Jimmy Kimmel, but he's not going to let anything slip about the worst kept secret in Hollywood right now -- that he's playing Aquaman in the next major DC comic book movie. Admittedly, though, he sure looks nervous about it.

'Jimmy Kimmel Live' host Jimmy Kimmel likes to have fun with his recurring "celebrities read mean tweets about themselves" segments, which always manage to be fun and strange and not too painful. Of course, if you know anything about Twitter trolls, you know that the tweets the Kimmel team picks are not nearly the meanest of the mean, they're just the right mix of rude and amusing. There are certainly much meaner tweets out there, and some celebrities actually want those.
