Charlie Sheen Still Poking Fun At 'Two and a Half Men'

Charlie Sheen still enjoys taking jabs at his old show -- posting this photo from the set of his new movie, with the caption ... "(this is at least TWO AND A HALF times more fun than my last gig..!)"

We're not going to do the math, but we're guess his last gig paid waaaay more than TWO AND A HALF times as much money.
