Creator Backlash: For Leonard Part 6, a movie he co-produced and co-wrote but ended up begging audiences not to see.
Creator Breakdown: Bill Cosby the Comedian died when Ennis did. Bill Cosby the Angry Old Man Who Mutters Invectives at Black Kids Who Wear Saggy Pants took his place.
Actually, the breakdown was evident as early as Those of You With or Without Children, You'll Understand back in 1986. That album has only three skits, the third of which is more of a commentary on how his children are growing up than anything else. The funny isn't that diminished, but he also spends a lot of time pontificating.
If his youtube page is any indication, Bill Cosby the Comedian is still there, just very reduced.
