Abbott and Costello were an American comedy duo composed of comedians Bud Abbott and Lou Costello, whose work in radio, film, and television made them the most popular comedy team of the 1940s and 1950s, and the highest-paid entertainers in the world during the Second World War. Their patter routine "Who's on First?" is considered one of the most famous comedy routines of all time, a version of which appears in their 1945 film The Naughty Nineties.
