If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

How would Jon Snow behave at a dinner party? Watch and see. "Game of Thrones" star Kit Harington was on "Late Night with Seth Meyers" Monday night, so Seth set up an SNL-style sketch called "Seth brings Jon Snow to a dinner party." In the 5-minute video, you see Seth with his NYC friends, then Jon in full Night's Watch attire. Turns out, he knows nothing about being a good dinner party guest. Or maybe it's everyone else who has it wrong. After all, winter is always coming. Eventually. If only Seth had invited Debbie Downer, she and Jon would really hit it off. Stay to the end, it's really hilarious.

Kit also talked, as himself, about GoT. He said he only read his own scenes for the new season. He usually reads the whole script but this time he wants to see what the hype is about. Kat Dennings, Michael Douglas, and Jon Cryer played charades with Jimmy Fallon on "The Tonight Show." Jimmy and Kat were partners against Jon and Michael. (Side note: How do we feel about Jon's shaved head?) In his own interview, Michael talked about how he had "a little mess" on his pants before his first appearance on Johnny Carson's "Tonight Show" 44 years ago. He was so nervous backstage and had a little pit stop before going out to talk to Carson. When he came out, he was told about his visible whatnot downstairs, so someone had to blow-dry his crotch before he went out. Backstage, Kat shared her worst audition story. She tested for a movie that later won Oscars. She auditioned for the daughter role and she had to hysterically cry in her father's arms. But the actor playing her father stayed across the room the whole time and she had to pretend to be restrained. That famous actor was later fired from the role, but Kat didn't get the daughter part. On "The Late Late Show," Jordana Brewster, Dave Grohl, and Rainn Wilson talked to James Corden about their Easters and various bands. They also did sketches of Jonathan, a nude older model. Just go with it.

"Mike & Molly" star Billy Gardell was on "Conan," and he said when he learned he got the TV show job he was doing stand-up comedy in the basement of a strip club with only $7.18 to his name. "Barely Famous" stars Erin and Sara Foster were also on "Conan" talking about disastrous dates and passive-aggressive parking tickets.
