The Smothers Brothers have been making people laugh for almost half a century, but their career has been built on sibling rivalry. Dick Smothers, one-half of the comedy team, says it was all an act.

It didn’t take long for the brothers’ initial folk singing act to turn into a comedy show, but after their witty remarks about President Johnson and racism on their 1967 show, “The Smothers Brothers Comedy Hour,” it was cancelled by CBS, despite being No. 1.

Dick talks with Growing Bolder about how he and his brother have kept their comedy relevant for almost 50 years.
