Plot summary
Peter meets Arthur Owens (Christopher Knight), an exact "double" of his with glasses, at school after making a date with a girl named Michelle (Kathy O'Dare). When Arthur makes a date with Pamela ( Denise Nickerson ) (a niece of Mike's boss Ed Phillips) while masquerading as Peter as a gag, Peter must enlist Arthur's help to avoid breaking either date. Carol and Mike catch on, but Pamela is actually attracted to Arthur, and Michelle is finally attracted to Peter.
