Live professional wrestling.
You know it's fake, everyone else over the age of eight in the audience knows it's fake, but it's so much fun and such a spectacle, even the bottom of the ladder local matches I saw last night, you get hooked and you can't help but whoop and holler.
I highly recommend going to see some live professional wrestling. It's a piece of genuine Americana that you'll really love if you stop being such a snob and give yourself over to it. It's in the same category as roller derby, once you go, you'll love it.
