One of the most original pieces of comedy ever written in the 20th century from the comedic genius of Abbott and Costello, it remains hilarious in the 21st century.

Introduced back in the 1930’s and based on an old Burlesque skit, the concept is simple, a baseball team with players names like ‘Who’ ‘What’ and ‘I Don’t Know’ and an inquisitive person asking about the team and the players. Thus, who’s on first? In which the person explaining would say, yes, because ‘Who’ happens to be the name of the first basemen.

Abbott and Costello perform the routine several times throughout their career, and rarely didn’t it the exact way each time.

The routine was named Best Comedy Sketch of the 20th Century by People Magazine, and since it was a baseball skit, it plays continuous on screens at the Baseball Hall of Fame in Cooperstown, New York.

There is also a recorded copy in the National Registry at the Library of Congress.

No matter how many times I hear this, it still remains hilarious.
