When McDonald's first brought in a clown to promote their vittles, he looked nothing whatsoever like he would later.
Here he is in his more traditional form, doing battle with Grimace, who was once evil and had four arms, if you can believe that. (Note the young Jodie Foster.)
Grimace later became a lovably dopey good guy. Here's one from my younger days, when he lost his voice. The doctor part of this still makes me laugh.
This may be my favorite of the ads, as Ronald does his level best to stay fah-resh.
Maybe it was better in its original Chinese.
