I remember an episode of Happy Days, for example, where Richie gets tickled by his girlfriend. My mouth almost dropped down to the floor when I saw that one, and all I could think about was how cool it was. (I always wanted to see Richie and Fonzie in a tickle fight but, alas, that was never meant to be.) I don't even think I had hit puberty at the time.
Either Laverne or Shirley tickled Lennie (the redhead--of Lenny and Squiggy) on an episode of their show.
And Jack often got tickled by a girl on Three's Company.
Yes, I was a very, very confused child!
But this stuff always made me feel warm and gushy.
