At Game of Thrones’ sixth season premiere last month, Dax Shepard and Kristen Bell showed up in matching tank tops — they read “Stark in the streets, wildling in the sheets” — and fake House Baratheon chest tattoos. As Shepard explained to Jimmy Kimmel Wednesday night, that was great … as long as they stayed together. Once they got separated, he was just a weird-looking guy who was very underdressed for a formal event. Lisa Bonet was aghast! Let this be a lesson: Guys, if you’re married, and you and your wife do any sort of “fun costume,” never venture more than five feet away from her. Pretend you’re magnets. Nothing weirder than a single dude in a silly outfit, no sir.
