Uncle Fester resembling Curly from The Three Stooges

As I was watching The Addams Family I couldn’t help but notice how uncle Fester looks and sounds a lot like Curly from The Three Stooges. Has anybody else noticed that? The resemblance is uncanny. He could’ve easily passed off as the stooge at the time for Curly’s replacement. I wonder if anybody gave it a thought at that time, but probably not until later.
