On the season one Muppet Show featuring Sandy Duncan, she is tickled by a tall purple monster on the sides during her first song. She giggles a bit during her song. Not a long scene, but cute.
Whether it is a myth or not that youtube removes the content if it is directly linked, I don't know. Is it really that difficult for you to press "backspace" once after you have pasted it.
Your welcome by the way (I assume you just forgot to say thanks for the info from Silentone and for me finding the clip).
