What is the big deal about Duck Dynasty?

I had a conversation with my friends today about Duck Dynasty. This TV show never existed in my vocabulary until I went to Walmart and saw Duck Dynasty clothing and accessories everywhere. One of my friends explained the show to me as "a bunch of rednecks who shoot ducks". I started to question others about the show and most people watched it because it appeared humorous to them. I didn't see the point of watching a show where men went out and used ducks calls to shoot ducks. It didn't make sense to me. Is my humor different from everyone else's?
