Answer
Comedian and actor Bud Abbott formed the popular double act Abbott and Costello with Lou Costello. The pair were known for their slapstick comedy routines and Abbott's signature phrase "Who's on first?" Their success in vaudeville, radio, film, and television made them one of the most successful comedy duos of all time. Abbott also pursued a brief political career, serving as the mayor of Burbank, California, from 1952 to 1956.
