This is old news, I suppose, but I didn't realize it until just now. I was watching a Katt Williams special, Kattpacalypse, on Netflix. It was funny, as stuff from this guy usually is, but then he started talking about Evolution being bullshit and Atheists being stupid. What? Well, I closed that video very quick. I get a large dose of stupid every single day on the Internet, but sometimes it's just too much too fast. That definitely qualified.
Here's a video I found showing that segment of his special and then an excellent rebuttal by Dr. Richard Dawkins. Have a look.
