Title: Abbott and Costello
Content:  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 early 1950s, and the highest-paid entertainers in the world during World War II. Their patter routine "Who's on First?" is considered one of the best-known comedy routines of all time. Their popularity waned in the early 1950s due to overexposure and changing tastes in comedy, and their film and television contracts lapsed. The partnership ended soon afterwards.

Abbott and Costello performed "Who's on First?" numerous times in their careers, rarely performing it exactly the same way twice. They did the routine for President Franklin Roosevelt several times. An abridged version was featured in the team's 1940 film debut, One Night in the Tropics. The duo reprised the bit in their 1945 film The Naughty Nineties, and it is that longer version which is considered their finest recorded rendition. They also performed "Who's on First?" numerous times on radio and television (notably in The Abbott and

Title: Who's on First?
Content:   "Who's on First?" is a comedy routine made famous by American comedy duo Abbott and Costello. The premise of the sketch is that Abbott is identifying the players on a baseball team for Costello. However, the players' names can simultaneously serve as the basis for questions (e.g., "Who is the first baseman?") and responses (e.g., "The first baseman's name is "Who."), leading to repeated misinterpretations and growing frustration between the performers.

Content:  "Who's on First?" is Abbott and Costello's signature routine. Time magazine (December 26, 1999) named it the best comedy routine of the 20th century. The sketch was based on other earlier burlesque wordplay routines. They began honing the routine shortly after teaming up in 1936, and performed it in vaudeville in 1937 and 1938. It was first heard by a national radio audience on March 24, 1938 when the team were regulars on the Kate Smith radio show. By then, John Grant had been writing or adapting other sketches for the team and may have helped expand "Who's on First?" prior to its radio

The team could time the routine at will, adding or deleting portions as needed for films, radio or television. The longest version is seen in "The Actors' Home" episode of their filmed TV series, running approximately eight minutes. A live performance commemorating the opening day of the Lou Costello Jr Youth Foundation in 1947 was recorded, and has been included in numerous comedy albums. The team's final performance of "Who's on First?" on TV was on Steve Allen's variety show in 1957.

After Costello recovered, the duo returned to MGM for Lost in a Harem (1944) then were back at Universal for In Society (1944), Here Come the Co-Eds (1945) and The Naughty Nineties (1945). Their third and final film for MGM was Abbott and Costello in Hollywood (1945). In 1945, a rift developed when Abbott hired a domestic servant who had been fired by Costello.

Content:  Abbott and Costello were signed by the William Morris talent agency, which landed them featured roles and national exposure on The Kate Smith Hour, a popular radio variety show, in 1938. The team's signature routine, "Who's on First?", made its radio debut on Smith's show early that year. Many of the team's sketches were further polished by John Grant, who was hired soon after the team joined the program. Their success on the Smith show led to their appearance in a Broadway musical in 1939, The Streets of Paris. The team was hosting a summer radio series in 1940 when they were signed by Universal Pictures for supporting roles in One Night in the Tropics (1940). They stole the film with their classic routines, including a shortened version of "Who's On First?" (the complete version was performed in The Naughty Nineties, released in 1945). The team's breakthrough picture, however, was Buck Privates, released early in 1941. They immediately became the No. 3 Box Office Stars of 1941. After working as regulars on the Edgar Bergen-Charlie McCarthy radio program in 1941–42, they launched their own show The Abbott and Costello Show, in October 1942.

Content:  While they had crossed paths a few times previously, the two comedians first worked together in 1935 at the Eltinge Burlesque Theater on 42nd Street in New York City. Their first performance resulted from Costello's regular partner becoming ill. Other performers in the show, including Abbott's wife, encouraged a permanent pairing. The duo built an act by refining and reworking numerous burlesque sketches with Abbott as the devious straight man and Costello as the dimwitted comic. Decades later, when AMC moved the old theater 168 ft further west on 42nd Street to its current location, giant balloons of Abbott and Costello were rigged to appear to pull it.
