"He seems to be retired now but, years ago in Vegas, I loved to go see George Carl do a comedy act that Johnny Carson (no stranger to great comedy acts) called "The funniest 20 minutes in show business." It basically consisted of Mr. Carl getting tangled in the microphone cord. For 20 minutes.
Ostensibly, he was there to play a harmonica solo...but before he got the first note out, he dropped the mike and then he had trouble with the mike stand. And then he knocked over a tray with his harmonicas on it. And then he somehow got the mike down his pants...and the more he tried to undo things, the more tangled and snarled and hopeless and hysterical things got.
I don't know how many times he performed it. I'm guessing 3 shows a night, 6 nights a week for 40 years. Those are very conservative numbers and it still totals out to 37,440 performances. Long before I saw him — near the end of a very long career — he had every second of the act perfected. Every movement, every gesture, every expression, he'd polished the way Nijinsky honed each step of Afternoon of a Faun. If there was a way to get a laugh in any given second of his performance, Carl had found it. A dead person would have laughed at that act — even one pumped full of formaldehyde."
