Stirling Silliphant demonstrates his comedy writing chops in this oddly-titled episode, satirizing several topical subjects. Surprisingly, the show hasn't dated after 60+ years.
It's styled as a showcase for child star Patty McCormack, self-consciously paralleling her inevitable transition from young toward adult roles. She's a goofy runaway who attaches herself to Maharis and Milner like a leech, and they prove to be soft touches for her kooky antics.
Among Silliphant's targets for spoofing are: the new-fangled digital computers, with Milner enrolled in a course at UCLA learning computer programming; TV detective shows, with Larry Gates quite amusing as head of the large Baer agency, with his reliance on scientific "follow the paper trail" methods mocked cleverly, in what is a prescient forerunner of the creation decades later of the surveillance state (with the help of the modern version of those original Univac type computers); and even his own dialogue style, as McCormack stretches Silliphant's fondness for spitting out non sequiturs and oddball allusions becomes comical this time.
Maharis is comically stuck as a bumbling door to door salesman pitching women's cosmetics, with statuesque B-actress Francine York striking in a small role as a horny would-be customer.
With the boys begrudgingly taking her in to stay with them in a males-only boarding house, Patty is fun cross-dressing for most of the show, pretending to be a man, dressed like one of the Blues Brothers. SS's script explicitly alludes to the boys in danger of being arrested for child molesting (Patty was 15 when this was shot) since the cops and Gates are looking for her as a potential kidnap victim, while he never wrote about possible assumptions out there about the boys having a homoerotic affair during their endless journey together.
