Bob Shreive was fantastic.  Man, that was about the only place to catch up with the Marx Brothers for a long time.  Often tuned in to his Past Prime Playhouse late movie back then.  Prior to that, he hosted Schoenling All Night Theater where, in between commercials, he would do skits (and probably down a few frosty glasses of the sponser's brew, given that he seemed to get more outrageous as the night wore on).
