'Green Day: Rock Band' Autographed Guitar Contest: Only One Day Left!

If you're anything like us, you spent most of Tuesday night playing a ton of "Green Day: Rock Band," taking control of one of the most dynamic bands in rock and shredding through some of Green Day's biggest hits like "American Idiot," "Geek Stink Breath" and "When I Come Around." (Our personal favorite is probably "She," which packs a speedy punch and is super-fun on all of the instruments.) You know what would make the "Green Day: Rock Band" experience slightly more satisfying? If you had a wireless "Rock Band 2" guitar for the Xbox 360 that was also autographed by Billie Joe Armstrong, Mike Dirnt and Tré Cool. Luckily, we have a way you can get your hands on just such a prize!

You only have a day left to enter our "Green Day: Rock Band" contest. All you have to do is record a video that answers the question "Why does Green Day rock?" Give us 30 seconds of video and upload it to Your.MTV.com and we will select the most creative, compelling and convincing video. You have until Thursday (June 10) at 11:59 p.m., and the winner will be selected on Friday (June 11).

There are already a handful of entries from excited Green Day enthusiasts looking to take home the big prize. We're looking for the most creative, inventive and passionate fans out there to impress us with the answer to the question "Why does Green Day rock?" Check out one of the current entries below.
