We "lovingly" called him Coconut Head. When he came up to bat, we'd yell, "Hey Coconut Head!". I can't really remember why. Powell got traded to Toronto and when I went to a few games there in 1982 at Exhibition Stadium (which I always thought meant an exhibition on how NOT to build a ballpark) I informed the few fans around me that his nickname was Coconut Head, which they thought was great inside knowledge and I instructed them on it's proper usage. So he came up to pinch hit and we all yelled, "Hey Coconut Head!" You could see him pause and slyly look around like oh crap, those dudes from Minnesota are here. I think he got a base hit. Good fun.
