I've heard Louis CK is one of the funnier dudes around, but I haven't heard his routine so I streamed it while I ate dinner. His comedy is smart, but I didn't laugh as much as I thought I would. I was thrown off a bit when he would laugh before a joke since I prefer more deadpan humor. His accents are also a little ignoring.
I'll check out some of his other stuff, but I much prefer Chappelle.
