I jumped on the bandwagon a little late, aka the summer after the second season ended. Since I watched this during the summer after the fall shows had ended and Psych had yet to premiere, I can honestly say I laughed harder watching this episode than I did in a really long time. Jim Parsons is perfect for Sheldon. The character he portrays makes the simplest acts, like cleaning a room, very funny. The lightsaber was another funny surprise, along with the low-pitched sound of voice. This episode couldn't have been better.
My mother is kind of stubborn when it comes to TV, meaning that she watches Supernatural and nothing else. But I sat her down and made her watch the first season, and she loved this episode, calling it her favorite of the season. Believe me, this is impressive because she hates to admit that she likes anything other than Supernatural. Way to go BBT, this episode just gained you two more fans :)
