Zac Efron Voices Adult Swim’s “Robot Chicken”

Zac Efron sheds his goody-two-shoes image to voice the character of lounge singer “Billy Joel” in this new clip from Adult Swim’s animated series Robot Chicken.

In the show, the 21-year-old former High School Musical star beats a sailor over the head with a beer bottle, dumps his body in the ocean and manically laughs about it.

Zac even gets to belt out his own rendition of Billy Joel’s “The Piano Man”! But in the end… his character gets brutally (but amusingly) stabbed to death.
