I saw Josh Blue on one of the first episodes of season 4 of Last Comic Standing and blogged about it: Not Easily Impressed (I fell off my chair laughing)
I kept on missing episodes and missed the finals but I've managed to watch a number of his clips on YouTube and I continue to be impressed by him. He makes me laugh out aloud each time I see him. Here are a couple of clips from YouTube. There are many more there. Just search on Josh Blue.
I had no doubt when I first saw him that he was going to win Last Comic Standing. I'm not sure how the voting went but I doubt that the others were even close.
