If you’re wondering what happened on the last episode of The Smothers Brothers Comedy Hour‘s original run, the answer is probably shorter than you think: Nothing. Because there wasn’t one.

Viewers who tuned into CBS on April 13, 1969 to see the Smothers Brothers — older brother Dick and younger brother Tommy — unleash their signature brand of sibling-rivalry comedy, socially relevant humor that pushed the censors’ buttons hard, and a roster of fresh and legendary entertainers who were more than game to cater to the Brothers’ mission … got Hee Haw instead.
