We think De Niro knows what he's doing and is just playing up for the laughs. He must be, right? He has two Oscars, so we know he can act, and we know he's funny so him having the most 'dad moment' ever caught on camera.
Twitter famous Vine user Jerome Jarre uploaded the video and called it 'ROBERT DE NIRO'S FIRST 6 SECOND FILM!' after De Niro allegedly starting messing with his iPhone, and if you're looking for a morning lol his Vine account is a treasure trove.
