Sheldon (Jim Parsons) is sure that a light-bulb moment is just around the corner in his research into dark matter proton decay. But the conditions in which a pathological perfectionist works have to be just right; currently his environment is too comfortable. So the guys delight in making life miserable for Sheldon, while long-suffering girlfriend Amy (it’s almost a contractual obligation to label her that) monitors his stress levels.

Sheldon’s sleep-deprivation hallucinations create a lot of fun, as does a running gag in which Raj is teased over his unhealthy affection for his dog Cinammon. And fans will enjoy another chance to hear the lullaby Soft Kitty. Purr, purr, purr.


Sheldon becomes concerned that his comfortable lifestyle is having an impact on his professional progress and is stopping him from achieving scientific greatness, so he asks the gang to make life more difficult for him. Meanwhile, Howard invents an unflattering game about Raj. Starring Jim Parsons and Simon Helberg.
