I've been up to my eyeballs in old TV shows lately, and while watching an episode of Three's Company, I was struck by one of those connections that was made in my 4-year-old brain. I finally realized who Mrs. Roper reminded me of when I was a kid.
Now, I wouldn't necessarily make this connection now, but these two will always be linked in my head. And while we're on the topic of Sesame Street, I can't see Snuffleupagus without being reminded of another character from another 70s ABC show.
I think it's the eyes. Snuffy and Al Molinaro have those sad eyes.
