I personally thought Rich Voss was by far the funniest of the comedians. None of them had just super strong material, but Rich made me laugh the most.The whole Ralphie May diatribe just didn't do it for me as comedy. The audience wasn't laughing, they were cheering because he hit a political nerve. This is supposed to be last "comic" standing, not last motivational speaker standing. If the audience votes for the funniest comic, then Ralphie won't win. If they vote for the one who says things they agree with and want to cheer for, then he's got it won.
I think lots of the posters here have formed an opinion of whom whey like the best and that is who they tout as funniest. I tried to put all that aside and watch the routines with a willingness to laugh at whoever made me laugh. That happened to be Rich Voss.
The bottom line is, I still think Dave was the funniest comedian in the house, and if you put all 10 on a stage and let them do 30 minutes, he would make me laugh the most by far.
