After Missing Links was cancelled, somebody gave Ira an inscription which he kept on his office wall: "PYHML", which it said stood for "Protect Your Health, Make Love".

Imdb gives Mike Gargiulo as director, so he and Ira were paired for ML while working on Play Your Hunch.
Soon thereafter, Ira was directing He Said, She Said with Howard Felsher producing.
I'm guessing that when it moved to ABC it originated from the Ritz (Walter Kerr) theater, as did Beat the Clock, Number Please and later, TPIR in glorious black and white.
