Christopher George guest stars as George, an old warlock boyfriend of Samantha Stephens. In her neverending efforts to break up her daughter's marriage, Endora summons George to romance Samantha. It turns out that Sam may be in just the right mood to be swept off her feet; she has just spotted her husband Darrin in an innocent but compromising situation with attractive next-door neighbor D.D. O'Riley (Beverly Adams). But when Sam ultimately declares her unswerving faith in Darrin, George responds by changing himself into a raven and "invading" Darrin's office. Written by Ken Englund, "George the Warlock" originally aired on April 22, 1965. ~ Hal Erickson, Rovi
