Abraham Lincoln in his years as a practicing attorney (from Carl Sandburg's Abraham Lincoln / The Prairie Years):

A fuddy-duddy judge corrected Lincoln's pronunciation of the word "lien" as "lean" saying it should be as "lion." In a minute or two Lincoln again pronounced the word his way, and again being corrected apologized, "As you please, your honor." And slipping again and the judge again correcting, he replied, "If my client had known there was a lion on his farm he wouldn't have stayed there long enough to bring this suit."
