Quote from Jill in Quest for Fire
Jill: OK. I'm all packed. How was the Tool Time? Randy: Amazing. Dad just launched a barbecue into space. Mark: Dad has been acting weird lately. Even for him. Jill: You're telling me. He woke me up in the middle of the night last night to talk about existentialism, vis-a-vis Tool Time. Randy: Dad actually used the term vis-a-vis? Jill: Oh, yeah. Then he had this great revelation coming out of the bathroom. "If a man flushes the toilet and no one's around to notice it, did it really flush?"
