To curb that binge drinking culture, DraftFCB decided to show another angle, you can still act like a drunken hooligan karaokeing and carrying on, despite not having more beers in you. No problem mate, just say Yeah, Nah, then chase down a bus full of pretty girls while tearing your shirt off. Imagine all the people, being sober but still acting drunk. It's easy if you try.
Warning, awkward bro-hug at the end.
