It turns out that you can buy his DVDs online, or just download a digital copy for $5. Let me tell you that this is money well spent. He is a Christian man so his jokes are clean, and although he does have some church jokes in there I think he's hilarious whether you're a Christian or not. We downloaded our first one last night and again laughed until we almost cried. We are for sure going to get all of them - it's the same cost as renting a movie but it's absolutely wholesome and clean fun...we truly have not laughed like that in years.
My only disclaimer is that I recommend watching only a few youtube links...quite a few are available for free, but they are portions of the DVD and are much funnier when they're in the context of the whole thing.
