Here's a commercial that aired regularly during Season One of Route 66 for the Chevrolet Biscayne. Appearing on boob-tubes across America in the Fall of 1960, the commercial features the cast from the then-new sit-com My Three Sons. One of the show's stars was William (I Love Lucy) Frawley, whose character Michael Francis "Bub" O'Casey predated William Demarest's Uncle Charlie. Frawley was on the show for five years, finally departing due to health reasons. Stanley Livingston also appears as Chip (these early episodes predate Ernie, played by Stanley's real-life younger brother Barry).
How do I know all this stuff, you ask? Because I grew up watching too much TV.
Oh yeah, in this commercial, Chip keeps asking - over and over and over - what a Biscayne is. He does it in such a low-key way that it's not as obnoxious as you might think. Soon, a little girl comes along, asks the same question and instantly gets an answer from Bub. The Moral of this Story is that if Chip wants attention, he'd better seriously explore the possibility of cross-dressing.
