Jimmy,
I've had that moniker since 7th grade when our baseball coach, Jerry Pfannenstein gave many of us our nicknames. Ducky was much easier than pronouncing my last name of Doetkott. One of my best buddies, Bogus Brook, nickname of Yogi, was probably one of the only guys that had a nickname when he arrived in Melrose. The rest of the guys, Mark "Kirby" Meyer, Dan "Tootie" Moening, Jeff "Grizzly" Adams and Dave "Hippie" Hinnenkamp I think were named by the coach. I think there were a few others, but now that I am 50, my memory is slipping.
Mike or Ducky
