This is just a funny clip from Jimmy Fallon featuring the awesome Simon Pegg as a drunk Ron Weasley wishing Harry Potter a happy birthday. Can I just comment on how much better every single Harry Potter movie would have been if Simon Pegg had been a cast member? Missed opportunity. Oh well, he’ll probably be old enough to play Dumbledore by the time they get around to remaking the series. And you know that’s going to happen.
