I imagine that many of you have seen these already, but just in case you haven't, here are some great videos that eviscerate the "science" of Ray Comfort & Kirk Cameron. Oh, and an interesting FYI - the guy who made the videos is a Christian.
Here's a place to critique Ray Comfort without being subject to his rules of censorship. We are a community of mostly atheists and agnostics, but theists are welcome to join. Sign up by emailing MacGyver Jr. - See his profile.
