In case you haven't seen it, it's cartoon about a little boy who's a "mad scientist." His older sister DeeDee is always annoying him and destroying his laboratory. In one episode Dexter competed with a rival scientist (a boy), while DeeDee had to fend off the affections of a pretty, long-haired blond boy.
I can recall the horror I felt at the end when the blond boy and the little scientist, heartbroken for different reasons, turned and stared into each others eyes, long & deeply, and then you saw HEARTS in them! The two boys held hands and went off in the sunset to "play" together. It was one of most disturbing things I've ever seen. I wrote to Cartoon Network, but got no response (natch). Now I just won't turn on that channel.
Got any insight into Jimmy Neutron or The Proud Family?
