Francis Mican had this on Facebook yesterday and it took me down memory lane. I remember watching this as a kid and it still resonates today. John John seems fascinated with Bert as a real creature and interacts with him as an authentic source. It's funny. I would be looking under the table at the strings and and wondering where the voice was coming from. Nope. John John trusts Bert and that he is the real thing. It's a classic.
