Quote from Wilson in Quest for Fire
Wilson: So, where is your splendiferous spouse? Jill: I don't know where he is. Lately, I don't know who he is. Yesterday when we got up here, he announced that he wants us all to move here. Wilson: Now that you mention it, he has been acting a bit odd lately. He told me the other he was considering becoming a part-time physicist. Jill: Tim? Wilson: Mm-hmm. Said he wants to contemplate the origins of the universe. Tuesdays, Thursdays and every other Friday.
