Leonard: Do you have a cousin Leopold?
Sheldon: No, I made him up. I think you'd call him Lee.
Leonard: I don't get it. I already told her a lie. Why replace it with a different lie?
Sheldon: Well, first of all, your lie was laughably transparent, where mine is exquisitely convoluted. While you were sleeping I was weaving an un-unravelable web.
Sheldon: Yes, if she Googles "Leopold Houston" she'll find a Facebook page, an online blog depicting his descent into drug use, and a desperate yet hopeful listing on e-Harmony.com.
