Have you ever noticed how Fred's hands seem to be shaking all the time. There are even a few episodes where he is trying to hold them steady. Now, I had heard that he had a drinking problem. Do you think that was the case?

Yup, we all know his hands shook all the time, but i don't know why. He never drank during the run of the series, or at least never enough to affect his work, that was the deal he and Desi had, the minute his drinking showed, he would be written off the show. But Desi said it never did anyway.
