"Pork and Beans" from Weezer's latest self-titled album, Weezer.
Internet geeks like me will love this. The video parodies the most popular viral YouTube videos, and actually manages to get the real "internet celebrities" to perform with them.
In case you're unfamiliar with any of the originals, a diligent YouTuber put together a handy montage. But before you cheat, watch the video and see how many you recognize.
