Alert, alert: Will Smith still has it. The star of the upcoming con man romantic comedy drama (co-ma rom-com-dram?) Focus hit The Late Show last night to chat it up with host David Letterman and, oh, yeah, to just randomly rap “Gettin Jiggy Wit It” alongside Letterman’s own band. Sure, most late night guests just walk out on stage, give a big hello, and sit down, but not Smith, who seemed determined to remind everyone of his rap roots.

The Tonight Show host Jimmy Fallon might be prone to brief spats of name-dropping – hey, the guy knows a lot of people! – but on last night’s show, it was at least somewhat appropriate. Still recovering from Sunday night’s SNL 40 super special, Fallon was eager to share his recollections of the evening with his studio audience (and also Questlove, who was actually there, but who charitably recounted the whole evening with the giddy Fallon). There were a lot of people there!

It's the moment we all knew would happen eventually -- and, based on the immediacy of the news cycle and when late night shows are actually filmed, it's the moment most of us also knew was happening yesterday -- but 'Daily Show' host Jon Stewart has finally announced his retirement after seventeen years at the news desk. Stewart's show films in the late evenings in New York City, so the news that he had announced his imminent retirement during a taping last night hit the wire many hours before the show actually aired.

Thank goodness for iPad apps. On last night's 'Tonight Show,' host Jimmy Fallon -- who grows more California by the minute, as the show has temporarily relocated to the West Coast -- and guest Will Smith decided to finally give the people what they want: rapping. Well, sort of.

Jeff Bridges really, really, really wants to help you sleep. The 'Seventh Son' star recently popped up during the Super Bowl, touting, well, something during a somewhat strange and somewhat soothing commercial spot. Turns out, Bridges is actually selling what it looks like he's selling: sleep. Wait, what?

Sigh. 'The Tonight Show' temporarily moves to Los Angeles -- Hollywood, Tinsel Town, The Big Grapefruit, only one of those is a real nickname -- and is suddenly just flooded with random star power. Zzzzz.

For the next week, 'The Tonight Show' is chilling in sunny Los Angeles -- the frigid cold of New York City, quite understandably, finally got to the crew, and also this has been planned for months -- and host Jimmy Fallon has spared no creative expense when it comes to making his temporarily Hollywood-based show look California cool. And we all know there's only one way to really drive home CA styling: 'The Fresh Prince of Bel-Air.'

Jimmy Fallon's 'Lip Flip' must be stopped. It has to end. Sure, the technology that drives this particular 'Tonight Show' segment is vaguely impressive (there are lips! and then they get flipped!), and Fallon and his various guests appear to have a good time pretending to talk out of each other's mouths, but the final execution is so terrifying, so weird, that it can only do one thing: cause nightmares.

Actors! They're weird! Johnny Depp may be one of Hollywood's brightest stars, but that doesn't mean he's immune to the weirdness of artistry -- in fact, Depp has kind of gone whole hog on this being "out there" thing, and it's very much a part of his process as an actor. Considering his box office cache and personal success, yeah, it's worked for him.

It's Water War! Jimmy Fallon's most bizarre and icy cold game yet! A game of chance, and um, hydration, Water War pits the 'Tonight Show' host against an especially down-for-whatever guest (after all, what sort of person would be okay with having water poured all over them on national television? a cool one, that's who!) in a battle to see who can get more soaking, sopping wet. That's the aim of the game, right? No? Then 'Blackhat' star Chris Hemsworth lost? What kind of world is this?!
