On The Tonight Show Starring Jimmy Fallon, the comedian brought out a drunk version of Ron Weasley, the hapless redhead from J.K. Rowling’s Harry Potter books, to gin up hype for the fictional hero’s birthday, which is July 31.

As expected, “Drunk Ron Weasley” acted like the worst birthday party attendee ever as he proceeded to chug a bottle of Jack Daniel’s, sob about how Hermione left him and make a lot of perverted jokes. Meanwhile, Fallon tried to keep him quiet (and clothed) so that the bad behavior did not ruin the magic of the series.
