From Japers Rink, as found on Taking Note:
Once upon a time, Dick was a common name. In fact, it was so common that when “Bewitched” needed to replace Dick York in 1969, it replaced him with Dick Sargent. Back in the 60s, Dicks were everywhere, including Major League Baseball. From Dick Allen to Dick Groat, Dick Brown to Dick Green, you couldn’t watch a game without coming across at least one Dick. Nowadays, however, there’s not a single, solitary Dick in the Major Leagues.
So, where’d all the Dicks go?
I think if a guy sat down and thought about it, one would find more than enough dick’s in the game.
