I have to admit that I am probably one of the only people alive in the U.S. that has never watched this show. As a 40 something person who grew up watching (and loving) shows like Happy Days, Laverne & Shirley, Mash, All in the Family, etc., I just can't stomach today's network tv programming with the laugh tracks.
However, on a flight home from Vermont, the in-flight entertainment (so they say) featured the Charlie Sheen program. While I did not plug in my headphones to listen, I did make an interesting observation.
Most opening credits to tv shows feature a producer or two, and perhaps an exec producer. The opening credits to T 1/2 M, ran for over 5 minutes. There was one producer after another. There must have been around 10 producers, including all the exec's. Producer is little more than excuse for someone to pay. Their contributions in many cases are minimal. Perhaps there are too many producers with their hands in that pie. Of course, that's just my opinion.
