The Bart, The

I remember watching Sesame Street when I was about 3 or 4 and a segment was on with Count von Count in a spooky castle with sombre organ music, cobwebs and bats flying around. I thought nothing of it but my aunt seemed to be a bit shocked that a children's show had "Count Dracula" (as she called him) in it. Kek.
