Weird Al Yankovic not only makes up musical parodies; he also plays a mean polka on his accordion.
Yankovic, dressed in a Hawaiian shirt, tight black jeans and turquoise sneakers, cavorted with a crowd of thousands Saturday night while playing the "Beer Barrel Polka" during the city's 24th annual Oktoberfest.
The audience chanted "Weird Al! Weird Al!" as they danced, drank beer and modeled chicken hats.
