When dd was playing 12U I called her pitches. Back then she could just blow it by most batters she faced, but of course I had to occasionally call a changeup -- being totally honest, I probably called more than I had to, but sometimes it's just more fun to strike em out on changeup. Anyway, my pitch calling did drive some of the coaches/dads a little crazy (in a good nature way), so dd's coach got in the habit of telling me before EVERY game, "No assing around, Nicholson!" and a username was born.
