Pranks! Wacky, silly, fun pranks! Destructive, horrible, embarrassing pranks. On last night’s Jimmy Kimmel Live!, former Saturday Night Live star Will Forte reminisced about a prank he once played on co-star Kenan Thompson, a generally benign (but charmingly so) prank that saw him and Kristen Schaal playing around in Thompson’s dressing room when he wasn’t present and then sending him pictures of the mayhem. This is a classic prank. What could possibly go wrong?

Why doesn’t everyone ask John Oliver for advice on everything? The Last Week Tonight host consistently thinks of the best possible answer for every possible question, so why not just turn him into the world’s all-knowing sage or something? The guy isn’t that busy, right?

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.

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?

Celebrities have feelings, too. Even when you think you're just talking random smack about them in the wide world of the internet (web?), you're still talking random smack about real people. If you're tweeting mean stuff? They might see it. And it might hurt them.

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.'

Well...not really. But, David Letterman couldn't help but bust Oscar Isaac's chops.

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.

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?!

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?
