For those who don’t get the still, Barney and Yoko Ono are in Moe’s. Barney orders a beer and Yoko orders a “single plum, floating in perfume, served in a man’s hat.” Moe immediately reaches under the bar, produces both orders, and says, “Here you go.”

Yoko Ono hasn’t worn her hair like that since the '70s. Didn’t come even close to guessing that was her. Is this a flashback and (also) are Barney and Moe changeless?
