I was wondering if any of you knew what happy days episode (or even season) it was where Ralph Malph walks in the room with a Big Fro on his head?

Also-- do you know a season in which the cast members of happy days wheres wide collared shirts? Also CHACHI--- I need him with his hair long and short-- I know his hair was shorter when he was younger int he beginning seasons but when did he start growing it out like neck length???

If anyone knows please reply ASAP

Thanks!
:crazy:

I think Chachi started growing his hair long after Richie left the show.
