Everyone but @TheAcademy. But @KevinHart4real is a terrific choice.— Patton Oswalt (@pattonoswalt) December 5, 2018
Kevin? My usual trio of writers are @MattOswaltVA, @GerryDuggan and @MikeDrucker. They're multi-nominated joke-slingers. You'd be smart to hire 'em. Just sayin'. You'll kill anyway but why not DEVASTATE? https://t.co/Y6Y0H9BszT
