Chris Farley may have been overly energetic. He was also an idiot. His goal in life was to be just like John Belushi. Well, at that he succeeded. And like Belushi, his entire adult life was a disgrace of wretched excess.
Somebody needs to say that, in loud and unambiguous terms.
And Phil Hartman was no role model, either. He was able to keep his personal life private, but anyone near him could tell he was allowing his world to fall apart. All the laughter in the world does not make up for or excuse that. Comedian and actor Robin Williams escaped the same ending, apparently because he had an ounce of common sense. But it should not have taken him a decade of abuse to realize that.
