Another frequent source of humor dealt with Jethro's endless career search, which included such diverse vocations as soda jerk, brain surgeon, Hollywood celebrity and secret agent/spy. Jethro coveted movie star fame, and relished becoming a "playboy" like Elly's sometimes beau Dash Riprock. Jethro's stupidity usually caused such career attempts to fail spectacularly, as when he decided to open a "topless" restaurant, where the waitresses did not wear hats. The one time Jethro almost succedes in anything is when "Cousin Roy" {Roy Clark} wants Jethro to support Roy be a country singer; Jethro refuses and loses as usual.
