YOU ARE CORRECT SIR!!!!!!!!!!!!!!!!
Just saw another baby boomer show of the same year, 1967,
Mr. Terrific. Mild mannered Stanley Beamish, worked at a gas station but his alter ego was Top Secrect Agent Mr. Terrific.
Anyone remember that show??????????????????
Ah the good old days of real TV in the Golden Age.
