a Johnny Hart cartoon

I remember time back way back when they were still playing baseball with a cubical ball. Someone (Peter?) hit a long fly ball to the outfield and the umpire (I'm pretty sure it was the fat broad) ran out to the ball, spread her arms out in a safe sign and said, "Six!"

There was some discussion of the strip on the editorial page in which a number of columnists for the paper (The Chicago Sun-Times, IIRC) nearly unanimously declared the strip funny but none could explain why it was funny.
