In the four-minute video, which was shot in one long take, the bleary-eyed star appears solo in a bar while in the throes of one gobsmackingly boozy bender.
We're not sure what's more awesome: the fact that he's dressed in a groovy Hawaiian shirt that makes him look like a wayward extra from The Descendants who ended up on the set of The Rum Diary? Or the fact that Radcliffe can convincingly channel one helluva drunk dude?
Watch as he stumbles around the bar, lip-syncs, jumps up on tables, plays air guitar and passes out—all while looking more ashen than Voldermort with an epic case of the stomach flu.
Tippletastic, you say? We'll raise our glasses to that, Danny boy—hiccup!
