Is it real? Well, no, of course it isn't. But is it a parody? I'm not sure! But it sure is funny!
EDIT: The more I look at it, the more wonderfully fake I think it is. Note that there's no real contact info other than a generic "info@" address. Also, no real advertising guy --even a Christian one-- would wear shoes that bad. I wonder what kind of priceless responses they've been getting?
