It's another pre-rape Broomsticks ad scene.
(click ad, via) Last time, the permanent press pants-wearin' gangbang guys played Rape Ring around Rosie. Today, the game is "musical pillows," where "everybody falls...for (ON) Lisa." Notes: Click the above the link, and you'll notice that these handsome, identically-dressed devils were definitely two of the Rosie rapers. Also, those pillows. But hey, "if you don't want to play our way—take off your pants and go home." The third ad in the late 60s campaign is decidedly less rapey.
