When I was little, I liked Sesame Street, the Letter People, Square One, Today's Special, Where in the World is Carmen Sandiego?, Eureka's Castle, PeeWee's Playhouse, and The Elephant Show with Sharon, Lois, and Bram. Wait, those are all puppets or live action....for cartoons, I'd have to saaaay..hm...ok, it's hard not to spout off the HUGE list of TMNT, X-Men, etc. cause those weren't meant for the little bitty kids. David and the Gnomes was on Nick Jr I believe, and I used to watch Speed Racer, Space Ghost, and Voltron with my brother.
I used to watch a lot of music videos when I was little too. My fave when I was a youngin was George Harrison's "I've Got My Mind Set on You". It's really silly now, but it was a lot of fun back then. I also used to like Madonna's "Vogue" and Paula Abdul's "Opposites Attract"- I was obsessed with cats. It was funny because I was too young to pick up on the sexuality of the Madonna one- I was always like, "Why is she on the floor drinking the milk? That belongs to the cat"
