Game of Thrones star Kit Harrington, who plays Jon Snow of The Night’s Watch, visited Late Night with Seth Meyers last night in anticipation of the Season 5 premiere airing Sunday, April 12th, at 9pm ET on HBO.

Check out the videos of his appearance here below, including one where host Seth Meyers brings Jon Snow to a dinner party.

Arrow star Stephen Amell walked onto the Late Night with Seth Myers set this week to extra piercing studio audience screams, fulfilling one of his goals of 2015. Host Seth Meyers commented on this unique situation because Amell had posted on social media in early January that he wanted to be on the show, and then Meyers’ “Twitter feed blew up.” A few days later the Meyers people called the Amell people, bringing them to the present. Meyers called it a “full hostage situation.”

Watch the video here below of Amell’s recent appearance on Late Night with Seth Meyers.

Jimmy Fallon made his last appearance last night as host of Late Night, the NBC late-night talk show he’s hosted since 2009. As his final send-off on Late Night With Jimmy Fallon, the 39-year-old Fallon performed with The Muppets doing The Band’s Last Waltz version of “The Weight.”

Check out the video of the performance here below.

Fallon now moves on to his new gig as host of NBC’s The Tonight Show, taking over for the departing Jay Leno, while fellow SNL alumn Seth Meyers heads to the helm of Late Night starting February 24, 2014.

One of the more unfortunate casualties of Conan O’Brien‘s messy departure from NBC as host of The Tonight Show, was that the network maintained legal ownership of all of the late–night talk show host’s many characters and bits he created over the near two–decade run he had there.

The most cherished of which would have to be Triumph the Insult Comic Dog, who gained his own cult following as a ultra–sarcastic field reporter who visited events, such as a new Star Wars movie hitting theaters, for example, where his hilariously poked fun at the many fanboys (and girls) who were camping out in line (a must–see if you have not).

During a recent airing of Late Night with Jimmy Fallon, Conan made a surprise appearance””on the very same set that his own Late Night was filmed for 16 years before he made the move to The Tonight Show and, ultimately, to Conan on TBS””to take back what was once his. But could there be a way for Conan to really get Triumph back from NBC somehow, or was this a simple bit of nostalgia?
