Wow, I just watched all of season 3 in three days. I thought this episode could have even been made into a movie. Simply fascinating. This is the episode where Lenard tells Penny how he met Sheldon and how the elevator went out of order. I can't believe I had missed this one in reruns, but I do enjoy watching them in order from the box sets.

My biggest regret is that I have to wait for my order of season 4 to arrive to continue my Big Bang Theory quest.

I think that right in here, around this episode to around Episode 4 of the next season ("Hot Troll Deviation"), this show reached a peak that few sitcom series have ever matched. Five of the six episodes are very close to perfect.

Made it up to the Hot Troll Deviation. Excited to watch it. Thanks for your comment.
