The Smothers Brothers were a duo of American folk singers, musicians, and comedians consisting of siblings Tom and Dick Smothers. The brothers' trademark double act was performing folk songs, which usually led to arguments between them. Tommy's signature line was "Mom always liked you best!" Tommy acted "slow" and Dick, the straight man, acted "superior".
