Was I wrong! They are both the same age, but it always made Scott Baio seem younger than Moran. I thought she was born in the 50s, but she was the same age as Baio. I don't know whether it was camera or what, but I always thought she looked much older than Baio and made Baio looked like 18 or 19, even though he was 21, though he still looked youthful compare to Moran. I know it doesn't make sense, but I always thought that.

When Chachi made his first appearance on HAPPY DAYS, Scott was much
SHORTER than Erin Moran. So, I thought he might be a few years younger.

Wow, you thought the same like me.

I think Erin was born in 1961 Scott a yr later. So Erin is older than Scott. Weird.

I thought the Internet Movie Database said they were the same age. If they said the wrong year for Erin, boy, were they wrong.

Oh......wow. I did not know that.:) Thanks for the info.

I think she looked older cause her dimples looked a bit like "laugh lines" as she aged

And Scott Baio almost looked like he could have passed for 17 or 18 at least...even though he was 21 years of age. But he looked almost ageless compare to Erin. Not to see anything bad to Erin, but it made Scott Baio seem like a kid still compare to Erin.

Well, that explains it.
