All I can recall is, it was in the first 2-3 years of the league. He played on one of the teams out west, KC, Houston maybe. We're talking about 55 years ago. Our
family was over to our grandmother's house for Sunday dinner. Had the game on & the play by play guy mentioned it during the game. That's all I can remember.
The reason was, that he used it for motivation, because teacher's salary was so low. It MUST have been low ! Because those players didn't get squat for money.
