I watched this when I was a kid (spanish version). The main character (Amigo, who is a cartoon version of a very famous actor and comedian, Mario Moreno "Cantinflas") was dubbed by a comedian named "Flavio" (artistic name).
Oh yeah, I remember this show, I watched the spanish version when I was a child. I liked it. The show was educational, Cantinflas(Amigo)usually met with some historical character on the episode. Galileo, Aristoteles, Columbus, Dante are the ones I can remember right now...
