No bowling shirt, no problem.
In the first peek at Ashton Kutcher
's debut on Two and a Half Men
, Charlie Sheen's replacement
leaves little to the imagination.
"All will be revealed," the sign held by nearly nude Kutcher, 33, along with equally underdressed cast mates Jon Cryer and Angus Jones, reads.
And for those wondering how Kutcher will fill Sheen shoes, producers say he won't be playing the bowling shirt-sporting, womanizing Charlie Harper.
"I can't replace Charlie Sheen, but I'm going to work my ass off to entertain the hell out of people," Kutcher said in May, when the cast change was announced.
Sheen was famously fired
from the CBS sitcom during a battle with the show's creator Chuck Lorre over his behavior on and off the set.
