Last night was Shane Battier's annual karaoke event, known as "Battioke," which in the past has brought us gems like Mike Miller and Chris Andersen singing "Ice Ice Baby." The highlight of this year's event was definitely LeBron James going all-out on "Back That Ass Up," with an assist from Michael Beasley.

There were some other noteworthy performances, including James Jones (not the worst singer) and Norris Cole doing "Holy Grail."

And here we have Greg Oden, Shane Battier, and Ken Jeong(?) belting out "I Want it That Way."

Looks like everyone had a pretty good time!
