For his second remote interview segment on Thursday, Seth Meyers threw to an empty screen. Well, it was a nondescript kitchen, watched over only by a pair of vaguely unsettling paintings. Soon enough, however, Meyers was treated to the sight of eventually revealed guest and scene-stealing all-star Jason Mantzoukas, striding into and out of Zoom-frame with the sort of triumphant fist-pumps most of us make whenever we turn on a movie or TV episode and see that Jason Mantzoukas is in this one.
