I was today years old when I realized that there was a straight up swinger scene in the Jim Carey live action version of 'How The Grinch Stole Christmas'. The party shows adults dropping their keys into a bowl. Seems responsible and innocent? Think again. This was a common part of mid 20th centurty adult themed swinger parties, where you pick up a random strangers key...and go home with them! Who know Whoville was so scandalous. Check out the video below for more jokes that went way over our heads as kids...and well, as adults.
