Fred Savage on The Wonder Years
Randolph Mantooth (Johnny Gage from Emergency)
Then Erik Estrada from CHiPs
Pretty much the entire cast of The Outsiders with Ralph Macchio being numero uno
Kirk Cameron, and then a few years later Mario Lopez. I am 36 now and I still have a crush on Mario Lopez
John Stamos when he was Uncle jessie on full house... ok not a child star but I'm counting him because he's beautiful LOL
Yep -- and before that, he was Blackie on General Hospital. Which reminds me of Rick Springfield when he was on General Hospital. Yes, I was a watcher during the Luke/Laura/Scorpio era.
And Mark Harmon, St. Elsewhere.
