where Biden looks down at his crib sheet, then stares blankly ahead, and starts to stammer out an incomprehensible sentence, followed by a second one, after which he says, "Look folks" and signals that he will now speak plainly and succinctly, only to unleash the most confusing, nonsensical statement yet. How about "Bidesnaps?"
