Robin Williams made me laugh as hard as any comedian. He could do that and then play some really great serious roles. The amazing thing was he would take all parts, small or big, and be equally as amazing at all of them. From the Genie on Aladdin, to Patch Adams, to the creepy dude on One Hour Photo - he nailed all the parts.
His Robin Williams on Broadway was the funniest stand up comedy I have ever seen. He was just brilliant - he jumped from different race, religion, to nationalities and offended everyone in the process. If you want to see comic genius, watch that performance.
Hate to see he couldn't get past his demons. Just can't ever understand suicide but I will not judge.
