Punk's not dead, it's just diversifying its portfolio. Having already conquered Broadway, East Bay pop-punkers Green Day are hitting the world of casual gaming with a new episode of Facebook's Angry Birds Friends that features pig opponents "inspired by band members Billie Joe Armstrong, Mike Dirnt, and Tre Cool." The offering also features "Troublemaker," an exclusive song that is most likely a tribute to the hard living ways of porcine egg thieves. Asked to justify his pro-swine stance, Pinhead Gunpowder member Armstrong answered, "We're all fans of Angry Birds. It's such an addictive game that when we first started playing it we couldn't stop. Go Team Green!"
