[pic=Green Day plays July 4th]042313_rockw.jpg[/pic]Want to see Green Day at the Rock Werchter Festival in Belgium this July, but haven't gotten around to picking up tickets yet? Luckily for you the festival is currently holding a contest to win a pair of tickets to the festival.

What's the contest you ask? To design the official Wapkin, Rock Werchter's official napkin. Now that's a pretty interesting contest if you ask me.

Head on over to Rock Werchter's official website for all the details. The contest closes on May 15th, the 4th anniversary of 21st Century Breakdown's release.
