The Smothers Brothers are Thomas ("Tom" - born February 2, 1937) and Richard ("Dick" - born November 20, 1939), American singers, musicians, and comedians. The brothers' trademark double act was performing folk songs (Tommy on acoustic guitar, Dick on string bass), which usually led to arguments between the siblings. Tommy's signature line was, "Mom always liked you best!" Tommy (the elder of the two) acted "slow", and Dick, the straight man, acted "superior".

The brothers were both born on Governors Island in New York Harbor, where their father, Thomas B. Smothers, Jr., a West Point graduate and U.S. Army officer, was stationed. Tom was born on February 2, 1937, and Dick was born on November 20, 1939. Major Smothers served in the 45th Infantry Regiment (United States) and died during World War II, while being transported from a Japanese prisoner of war camp in Fukuoka, Japan, to a POW camp in Mukden, Manchukuo. They were raised by their mother in the Los Angeles area.  They graduated from Redondo Union High School in Redondo Beach, California, and attended San Jose State University. After a brief time in a folk group called the Casual Quintet, the brothers made their first professional appearance as a duo in February 1959 at The Purple Onion in San Francisco. They were a popular act in clubs and released several successful top 40 albums for Mercury Records, the most successful being Curb Your Tongue, Knave! in 1964. Their first national television appearance was on The Jack Paar Show on January 28, 1961.  The brothers appeared in a segment of the television series Burke's Law, in 1964, in which they played two compulsive hoarders. Their first television series was a situation comedy, The Smothers Brothers Show (1965-1966). Tom played an angel come back to earth to oversee his brother Dick, who played a swinging bachelor. It did not do well in the ratings and had little of the music that was identified with the brothers. Tom would say in 1969 that "Four Star gave me ulcers."
