Felix Ungar:  What freeway are we supposed to be on ?
Oscar Madison: The 405 .
Felix Ungar: I think that sign back there said _ 101 _ .
Oscar Madison: If you did n't have the brains to pee back at the airport , how could you possibly read that sign ?
Felix Ungar: Reading and peeing are two different things !
Oscar Madison: At your age you 're lucky you can do either one .
