Big Bang Theory Quote
(a comment Penny made has given Leonard second thoughts about going on the Arctic expedition)
Sheldon: Her missing you is an emotional state you find desirable.
Leonard: Yes, obviously.
Sheldon: All right. Well, given that missing you is predicated on you leaving, logic dictates you must leave.
Leonard: Yes, okay, but I'm gonna be gone for three months. What if she doesn't miss me that long and she meets someone else?
Sheldon: She does have a short attention span.
