Well, you might find one where an old man is trying to carve the turkey but keeps messing up in a funny way. Another could be him getting lost in the Thanksgiving parade and having all sorts of hilarious adventures.
The old cartoons featuring old men tend to have slower-paced stories. They might emphasize life lessons or show how the old man's wisdom helps solve problems. The characters are often drawn with distinct features to make them memorable.
It depends. If the cartoons don't violate any copyright or defamation laws and are created within the bounds of legal and ethical standards, they can be legal.
