There are actually several quotable lines from that movie that I inundate my family with frequently.
"I have no response to that". (I do that one frequently.)
"Luggage. It is the central preoccupation of my life". (Said anytime we get ready to go on vacation, and upon return): "Wherever we go, and whatever we do, we're going to take this luggage with us."
(Occasionally when my wife says "I love you.", I respond with): "I love you too. It's great. I'm happy......but the timing sucks."
"Brain Cloud"
"Do you think I feel good? Nobody feels good. After childhood, it's a fact of life. I feel rotten. So what? I don't let it bother me"
(and anytime we go camping and are out amongst the stars, I break out) "Away from the things of man, my love. Away from the things of man."
