Ghost Hunters is a great show. Agree I like when they are able to debunk some things, but other things not. I also like the fact they aren't afraid. The recent addition of the two girls is rather amusing.
As for Ghost Adventurers, I quit watching it, it was too hokey, too stupid, and idiots that I want to slap upside the head a few times.
I did catch the brick flying incident and was slightly amused by the reaction of the guy who was watching the tape afterwards.
