Rowan & Martin's Laugh-In producer mollified him, but had announcer Gary Owens read Johnson's credit as a separate sentence: "Starring Dan Rowan and Dick Martin! And Arte Johnson!

It was hosted by comedians Dan Rowan and Dick Martin. "Laugh-In" originally aired as a one-time special on September 9, 1967, and was such a success that it was brought back as a series, replacing "The Man from U.N.C.L.E." on Mondays at 8 pm (ET). The title of the show was a play on the "love-ins" or "be-ins" of the 1960s
