The shows on TLC are all fake, its manufactured drama, look up Breaking Amish.
As for the History channel shows, while I would love to believe all kinds of people bring in those fasinating items into Rick's pawn shop, part of me feels most of those people are actors bringing in props. Its just too slick a production. Same with American Pickers. I read somewhere those 2 guys were upset when they found out the most popular person on that show was the lady with all the tattoos and History wanted her featured in the show more.
I still believe Deadliest Catch is 100% real, you can't load crab. I think they manufacture drama, but that show would be hard to script fishing wise.
