I included more of the text, and it puts the sitcom part in context, that this guy was mean and threatening towards Ben Stein, thereby revealing him as a liberal 'Rat. That leaves out guesses like Cosby and Grammer, it would seem.
Can you think of a sitcomer, with a family violence factor, who is a lib-Dem Republican hater?
"That leaves out guesses like Cosby..."
Actually Cosby isn't such a bad guess, he can be pretty nasty, and I've seen him a few times when I thought he was a little stewed, remember that op ed his wife wrote after their son was killed, blaming America for teaching the immigrant murderer to hate blacks. The killer was from somewhere in Russia or thereabouts.
But I sincerely doubt that Ben Stein has more money than Bill Cosby and I'm sure Bill Cosby would be the first to be fully aware of that!
