Quotes (22)

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, Sheldon wins.

Howard: So you can never take it (the sweater) off?
Leonard: No.
Raj: Not even to sleep?
Leonard: No.
Howard: So you're just an idiot?
Leonard: It's called proving a point.
Howard: Is the point you're an idiot.

Howard: The man impersonating a bear would like you to know that "Only you can prevent forest fires."
Raj: I don't get it.
Howard: You didn't have Smokey the Bear in India?
Raj: No. Was he anything like Munmun the Mongoose? He taught us not to play with cobras.
Howard: You had to be taught not to play with cobras?
Raj: You had to be taught not to burn down the forest?

Penny: See, just now you expressed your feelings to my face. How come you could do that with me but not with Raj?
Lucy: I don't know your email.

Penny: If you guys were hungry, why didn't you order something at the restaurant?
Bernadette: We did. You never brought it.
Penny: Oh, that's right. Nachos and a turkey club.
Amy: Not even close.
Penny: Well, I was too busy standing up for my friend to worry about your ... I want to say salmon.
Amy: You want to say sorry.

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
Shirley Junkin Canada, 13:31 Nov 15 2013.
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.
