It's weird, cuz I watched the first 6 or 8 seasons, then stopped watching.
Then, I got back into it about Season 11 or something. I felt like I couldn't possibly catch up, but I'm back into the swing of it now, and if they refer back to something that I maybe missed, I can always google it so find out..
BTW.. I literally just posted here, and then it was halfway down the page. This place is mental tonight!!!
