Felix il gatto

As I recall, the words to the theme went: "Felix the Cat, the wonderful, wonderful cat. You'll laugh so much your sides will ACHE. Your heart will go pitter-pat watching Felix, the wonderful cat."

I watched this TV cartoon series regularly as a child in the 60s. I enjoyed it a lot, but I believe I never suffered from aching sides. In fact, there were a few things about this show that were a little bit creepy, such as the sinister Master Cylinder, and that lantern-jawed kid Vavoom, who could blast through anything by just shouting "Vavoom!" That's the kind of stuff that creeps into the dreams of young kids and gives them nightmares!
