Why cover "Womanizer," asks All-American Rejects' Tyson Ritter? "Because of its deep political connotations? No. It's because we can do it better than Britney." Then the frontman breaks out the polka-style hand organ and the band digs into an eerie acoustic rendition of Spears' hit from Circus (with a dash of "Happy Together"). Toss Madonna and a mustache in there, and Tyson is the new Eugene Hutz (of Gogol Bordello fame). Watch the performance (from Yahoo!'s Pepsi Smash show) above. Extra points to the band for using beer bottles as percussion.
