I would have thought the same thing about the show's viewers. But, it's just a hunch. I've never seen it.
Man... You DON'T KNOW what your missing! I'm sure it's not everyone's cup of tea, but it's fun to watch a lot of these clueless people who think they can sing!
It's kind of like going over to DU to watch the zoo. I guess if you don't enjoy clueless people saying and doing DUmb things, you probably can't appreciate such mighty fine TV!
