You mean Jack Douglas and Reiko. They were on Jack Paar's show a lot, as I recall.
I stand corrected, and I do remember the Paar appearances. Was there not a comedian named Jack Carter? I recall Monty Rock III being another staple of Merv's show in the late 60s. Remember Sam Levenson? And that cranky guy Henry Morgan? Another one-tick pony comic who used to appear on those shows was Jackie Vernon. And the never-funny Donna Jean Young, whose whole schtick was that she was from East McKeesport, PA. Man, too much of my youth wasted in front of the tube. Now I go weeks without ever turning it on.
