I've seen it and watched the last four seasons after missing the first few. Even thought we pretty much know what's going to happen and parts of the show are very cheezey I still love it. Can't wait until it starts.
Funny stuff. I started a thread years ago on another site called, "What would Jack Do." where people would post scenarios like "Jack gets put over a barrel at the auto mechanic." or "Jack gets bumped while waiting for a table at a restaurant." We had a lot of fun with that.
