Does anyone remember this Sesame Street story from the late 70's? David was coming to work, until he saw a huge banner on Hooper's Store. "Home of the Hooperburger Haven." Mr. Hooper called David in and it showed Mr. Hooper wearing a striped red and white coat and a flat straw hat. He handed David another coat and hat and told him that he was changing the store into a hamburger place. Mr. Hooper also hired a quartet of anything Muppets dressed in the same coats and hats and they sang a Dixieland-like song about Hooperburgers. Some of the adults came into the store and Mr. Hooper told them about his Hooperburger idea. But nobody was interested in burgers right now. They just wanted other things from his store. Soon, Mr. Hooper hung up his hat and coat and told David he was canceling the whole Hooperburger thing and just make it his regular store. But when he said, "Hooperburger", a family of anything Muppets came to the window wanting burgers. Mr. Hooper tried to tell them that he wasn't in the burger business anymore, but the family kept shouting things like, "Extra cheese!" "No pickles!" "Lots of onions!" At the end, Mr. Hooper told David not to mention the word, Hooperburger anymore. But then the singing quartet appeared and said, "Did somebody say Hooperburger?" And they all started singing that song again while Mr. Hooper and David tried to stop them. And they kept singing during the "Sesame Street and Children's Television Workshop", credits.
