Wow, just when I thought The Big Bang Theory couldn't top themselves they do. Another unbelievable episode jam-packed with Sheldon greatness. His chemistry with Penny has been well-documented and we had another entertaining scene with them in the car together, including Sheldon thinking Penny telling him to get out meant for him to look under the hood. We had Sheldon screaming on Howard's motorcycle and asking Raj to take him on a plethora of errands when the two drove together.
I don't think I can remember the last time I laughed so hard while watching a comedy. There were some cliches like the intervention, but the writing is strong enough to overcome those potholes. The show always keeps you guessing, like the reference we got at the end too. Just another series classic and another great one for Season 2.
