There's no fool like an old fool

There's no fool like an old fool.

Prov. Cliché Old people are supposed to be wise, so if an old person behaves foolishly, it is worse than a young person behaving foolishly. As old Mrs. Fleischman watched her husband try to dance the way their grandchildren danced, she muttered, "There's no fool like an old fool."
