Misinterpreting a chance remark, Tabitha transforms 32-year-old toy salesman Irving Bates (Ron Masak) into a nine-year-old boy (Richard Powell). Unable to undo the spell, Tabitha's parents, Samantha and Darrin, are forced to unofficially adopt the junior-sized Irving. The solution to the problem rests with Irving's jealousy concerning his grown-up girlfriend, Ruthie (played by former Munsters regular Pat Priest). Written by Jerry Mayer, "Just a Kid Again" was first broadcast on February 26, 1970. ~ Hal Erickson, Rovi
