This week marks the 40th anniversary of Sesame Street. I've been showing the kids clips on Youtube of the original Sesame Street bits, and this one is definitely our favorite. The kids laugh hysterically and then beg to watch it again. And now, whenever Campbell sings the ABCs, someone yells "Cookie Monster" at random intervals, which drives Campbell insane. "Dat's not how da song goes," he yells, while we all laugh.
