I only came to the series this summer, when I picked up the season one dvd's on sale. I watched the entire season one weekend, and laughed so hard I think I built new ab muscles. I went through season two and three (bought on iTunes before the dvd's came out) within a few weeks, so I'm only watching this season as it airs for the first time.
That said, Season Four has been solid, culmanating in last weeks episode that I think has been the best so far (Sheldon and Gorn infested REM sleep? Sheldon and the shot?
) It's had the highest ratings in Canadian televison history
Not to mention, that I had like a mini-comicon with Jim, Kunal and Simon when they came to Toronto to film our entertainment show, eTalk. I managed to get backstage, and was in the background on eTalk and most media pictures, just behind Jim's left shoulder
