Drunk Ron Weasley sings 'Happy Birthday' to Harry Potter

As any good witch- or wizard-wannabe knows, the Boy Who Lived isn’t much of a boy anymore. In fact, he turned 33 yesterday — on a date that also happens to be Harry Potter mastermind J.K. Rowling’s own birthday. (There must be some powerful magic at work every July 31.)

Naturally, Harry’s fans and celebrated the big day by writing fawning online tributes, making elaborate cakes, and admiring all seven of Kazu Kibuishi’s new covers for the series. And then there was Harry’s best friend Ron Weasley, who decided to fete his friend by singing a special song on Late Night With Jimmy Fallon… and chugging something that looks a little stronger than butterbeer.

Poor, poor Ron — he can’t even afford the rights to ‘Happy Birthday’! Simon Pegg, on the other hand, probably could.
