You know nothing, Jon Snow — especially proper dinner party etiquette.

This hilarious clip from Monday night’s “Late Night With Seth Meyers” shows what would happen if you brought Jon Snow (Kit Harington) — who has suffered through a bastard childhood, plodding through the hellish world beyond the wall and being shot at with arrows — to a civilized Manhattan dinner party. Turns out the contents of your typical “Game of Thrones” episode — murder, betrayal, lots of incest — don’t make for good conversation fodder.

“Work has been very stressful,” Snow says, apologizing for his behavior.

Season 5 of the hit series debuts Sunday night on HBO.
