Yoda and The Muppet Show references
The only reference to Yoda I can think of is in the movie E.T. The Extra-terrestrial, when the kids take E.T. out trick-or-treating and a kid dressed up in a Yoda costume walks by. And of course, when Elliot makes his brother "give him the power" (i believe that's a Dungeon & Dragons reference, which was huge in 1982, but I don't get into it) and his brother says "Yes, hmm, you have absolute power" in a perfect Yoda imitation.
Also, a gigantic Muppets reference was made on The Cosby Show, in 1990, as a tribute to Jim Henson, when on the episode "Cliff's Nightmare", Cliff has a wild dream where he meets Muppets like Sweetums, Digit, and even Gonzo! They want him to do deliver babies at the hospital and lots of familiar Muppets pop up. Look for the episode on WGN or Nick at Nite. It's very funny.
By the way, in reference to whoever posted about Growing Pains, the show ROCKS! and I care when someone kisses a woman who's not his wife! Looking at another woman with lust in your heart is a sin.
It's called adultery.
