Sheldon: I sense judgment on your part.
Leonard: No, no. Maybe a little.
Sheldon: May I suggest that your criticism is based on jealousy.
Leonard: Jealousy? What do I have to be jealous of?
Sheldon: I have a functioning and satisfying relationship with a female. You have none.
Leonard: Oh, right. That.
Sheldon: Jealousy is an ugly green-eyed monster, not unlike the Hulk, who, by the way, also has a girlfriend. In this iteration, Jennifer Connelly, whom you may recall as the girlfriend of Russell Crowe in A Beautiful Mind, a feel-good romp if there ever was one.
Leonard: I'm not jealous.
Sheldon: Hurgh! Leonard not jealous.
