Let's see there was no

Al
Chachi
Joanie
Richie
Ralph

1982-83 season gets my vote.

i have to agree with you there. i didn't exactly like the series after Richie, and Ralph left but it just got worse when they tried to replace Richie with Roger, and Chachi with Flip. the only thing i liked about it was that they brought back Arnold.im glad that Chachi and Joanie returned for the last season
