Aunt Clara's warlock boyfriend, Ocky (Reginald Owen), is tired of having his British castle-hotel haunted by a pesky ghost named McTavish (Ronald Long). Troubleshooting Samantha manages to exorcise Ocky's establishment, only to have McTavish move in with the Stephens family, wails, rattling chains, and all. Meanwhile, Ocky suffers a drop-off in business when the customers -- including Darrin's parents -- complain that they miss old McTavish! Written by James Henerson, "McTavish" originally aired on February 15, 1968. ~ Hal Erickson, Rovi
