Well the story I heard was that on their first date Old Joe and his wife-to-be were having sex. As Joe got in the short strokes his Lover-at-the-time (same broad) started shouting at the top of her lungs, " Drive it home Joe, I am a spy". I guess she thought that would turn him on. Right after that Joe showed up everywhere bragging about screwing a CIA agent.
You forgot to add - "Anyway, that's how I heard it." 8-)
Not exactly a small group he'd joined.
