Perhaps one of the funniest sketches of all time is Abbott & Costello’s Who’s On First? Even if you do not like baseball, you have to laugh. Abbott & Costello performed it both on radio and television to great acclaim. While the routine was copyrighted, they never performed it quite the same way each time. Sometimes the names or nicknames of real players were tossed in or referenced. A gold record of the sketch is at the National Baseball Hall of Fame in Cooperstown, New York. Time magazine in 1999 named it the Best Comedy Sketch of the 20th century. There have been other imitators, of course, some done to parody the sketch. The original though still is the best. And whether performed on radio or television never failed to entertain.
