Seems like a bunch of them went on to do Boy Meets World!
Ronnie Pinsky (was that his name?) -- anyway, the salami guy who took over Michael's role, he did a bunch of episodes for Boy Meets World in the early years. He played one of the bullies.
Telly (the really athletic one) was in Sister, Sister, Smart Guy, Boy Meets World and Family Matters.
Dina played Eric's interest in...you guessed it, Boy Meets World. I remember her doing skin commercials too.
I had the biggest crush on Michael! Too bad he was only on for one season.
Nickelodeon shows today just aren't the same.
