This episode was a good way to illustrate how people with OCD really feel. The feeling is something they can not control and it is sometimes actually painful. I was hoping this would help viewers understand this problem.

Bring Lucy (Kate Micucci) back and make her a regular.... PLEASE !! Luv the Show.... best on the air !

Yes - needs fresh or returning characters. Sheldon's mum or Leonard's mum were always entertaining,

This episode was not funny. Leonard really should have hit Sheldon and it is high time that he moved out. He no longer needs Sheldon as he is no longer a nerd, and Sheldon's utter inability to learn anything is staring to wear thin.

This episode was rubbish! What's wrong with Sheldon. This was not funny at all, how can someone lying their ass off and then making their best friend suffer forever it's horrible! Why did't Leonard punch Sheldon in the face?! But I still love this show!!!! X

Nice,Good luck Lucy& Raj

Molaro, Prado, Reynolds were the writers of this episode.... I'll seriously consider missing any more of the episodes these three write. It was dragged down....
jennifer United States, 12:15 Nov 15 2013.
I was very disappointed in the writing. The storyline about Leonard not returning the video was never really explained properly and then Leonard's pestering Sheldon about how he shouldn't "freak out" when he already said he wasn't going to seemed forced.
Amy United States, 11:40 Nov 15 2013.
Not the best episode. Sheldon so cruel! Amy should have said more than "Sheldon that's diabolical." She should have berated him for his cruelty.
