I was very sad to hear that Captain Kangaroo has passed away. Of course, there already is a whole generation who did not know the joy of Captain Kangaroo, Mr. Green Jeans, Bunny Rabbit, or Mr. Moose (my particular favorite). How sad to think they have been replaced with things like SpongeBob SquarePants. Of course, I would argue that the Wiggles are a valuable addition to our pop culture, and I'm sure my son would agree...he's 20 months old and can recognize them on sight.
