"Gun-Shy" was a spoof of the long-running Western television series Gunsmoke, on which Clarke performed as various characters in a dozen episodes between 1956 and 1963, although most often in the recurring roles of Dodge City's hotel clerk Mr. Dobie and the town's bank manager Mr.

His final television performance is on another Western series, Destry with John Gavin, in the 1964 episode "The Last Girl from Gemmorah", which aired on ABC seven months before Clarke's untimely death.
