Charlie Sheen told a Boston radio show this week he's in talks to return to Two and a Half Men, but the story doesn't end there.

Sheen filed a $100 million lawsuit against Warner Brothers and the show's creator for giving him the boot in the first place.  So it's unlikely he could just show up and start working again. 
In the meantime, he's touring the country with the Violent Torpedo of Truth/Failure is not an Option Tour, getting booed in some places and cheered in others.  That tour stops in Dallas April 27th if you want to buzz on over and check out the Sheen antics for yourself.
Winning, duh!
