I teach 8th graders in Michigan. Every year our school takes 100-200 of them to Washington DC via motor coach busses. My colleague once noticed that he could spontaneously begin a sing-along at any part of the trip by grabbing the bus mic and humming the first few bar of the ma-nah- ma-na song. No matter For over 15 years now, it works without fail, the majority of kids will join in the melody. Everyone associates the tune with the Muppets, but no one could be any more specific. I’ amazed of the stickiness of this obscure, but at the same time, near universal piece of American culture. (Sort of like Rick Astley) This struck me this year,as I’m recovering from an ablation surgery I had on March1, to remove cancerous brain cells. I unfortunately must skip this year’s DC trip:(.
