NOW IS YOUR CHANCE!!! In two weeks, CBS's excellent The Big Bang Theory returns for Season 3. Have the first two seasons passed you by without making themselves known? A pity! Take this opportunity to watch the first two seasons by illegally downloading them off of the internet or watching what is available legally on the CBS website. Either way, watch what you can and get caught up before the Season 3 premiere on 9/21, at the new time of 9:30pm.
