As inveterate watchers of sitcom reruns (and a real-life Felix/Oscar combination), my sister and I loved The Odd Couple while we were growing up. One of our favorite episodes featured a courtroom sequence in which Felix (Tony Randall) berates a witness to “never assume,” and proceeds to use the chalkboard to demonstrate what happens when you do. More years later than I care to admit, the mere mention of the word “assume” makes me smile.
