Of course, one of the biggest laughs in The Odd Couple is:
Oscar (to Felix) "You leave me little notes on my pillow. I told you a hundred times, I can't stand little notes on my pillow. 'We're all out of Corn Flakes. F.U.' It took me three hours to figure out that F.U. was Felix Ungar."
A laugh that literally stopped the show at the Huntington Hartford.
