Spoof on Ghost Hunters?

I stopped watching SNL and MadTV years ago so I don't know if anyone has done a spoof of those ridiculous ghost chaser shows on syfy.com. It would be shooting fish in a barrel. I can't help but LOL when I stumble over those shows. I'd like to know what the average age of the audience is. I'm guessing the same ppl who watch Ghost Hunters also watch the WWF and think it's "real."
