Whereas Robin Williams in his cocaine-fueled hey day of controlled insanity was always that nano-second away from taking something and improvising it into usually more than one thing, Bill represented people more because he would dive into topics of interest that most could relate to. The best way to imagine his approach is for us to remember those times when someone, usually a boss or someone we can't talk back to, does or says something that really pisses you off. We, for the most part, keep it to ourselves or compromise it in some way. Not Bill.
He died, unfortunately, of pancreatic cancer in 1994 at the age of 32.
Instead of more talk why not cut to the chase. Here's Bill from an HBO show in 1991 and he's speaking abut Marketing and Advertisement.
Think he might be a little relevant today? (Thanks for the reminder DB)
