Due to our ethnic backgrounds a number of us will appreciate this. Ted was a very large man who played first base primarily for the Cincinnati Reds. He was an imposing physical specimen with very large arms that he showed off by playing with his shirt sleves rolled up. And he could crush a baseball.
From time to time Ted would flex his muscles and make a very large fist, asking if anyone knew what it was. If the answer was no, Ted would reply, "This is my Polish joke stopper!"
Hey have you heard the one about the big, dumb Cincy 1st Baseman?
But probably best if you phoned that one in.
