Mah na mah na.

Sorry for everyone who's going to be singing this for a week.
I also remember them singing Up Up and Away.
I'm not sure if anyone else who remembers super old school Sesame Street (I'm talking when the original Gordon was still on) agrees with me, but some of those sketches really take on new meaning when you get older. Like maybe Mr. Hooper had some "herbal remedies" for sale at his store.
