On Father's Day, June 21, 1964, Philadelphia Phillies pitcher Jim Bunning pitched the seventh perfect game in MLB history against the New York Mets. In the ninth inning of that game, Bunning called his catcher, Gus Triandos, to the mound. What did they talk about? Triandos stated after the game, "He said I should tell him a joke, just to get a breather. I couldn't think of anything. I just laughed at him."

This Rawlings official National League baseball is signed by both Jim Bunning and Gus Triandos in blue ballpoint pen. This ball includes a Great Moments COA.
