Re: TOS Costumes on Mork & Mindy.....
Around the exact same time MORK was on the air, actor Phillip Pine(Green on TOS)was on the solo spinoff of SANFORD & SON in an episode about Fred being called for jury duty. But by then Pine's hair was almost totally grey and he would have looked radically different in his old Colonel Green jumpsuit.
Remember what cooleddie74 says, kids:
