Leave it to Conan O'Brien to give the world TV's first lesbian zombie kiss. Yes, you read that right: TV's first lesbian zombie kiss.

The talk show host welcomed the cast of The Walking Dead—it's a little show on AMC about the zombie apocalypse, you might have heard of it?—on Conan, and marked the occasion with something he claims has never been done before: lesbian zombies kissing. It's a true historical TV moment that you have to see to believe.
