Billy Ripken had a decent major league career as an infielder, but nothing close to the career enjoyed by brother Cal Ripken Jr., baseball’s all-time iron man. But this “error” baseball card of Billy lives on in infamy. Apparently nobody noticed the little x-rated message on the knob of the bat he’s holding in the picture for this card. One story says that writing “f**k face” on his bat was a prank pulled off by teammates, although Ripken says he wrote the message on the bat to distinguish it as one of his batting practice bats so it wouldn’t get mixed in with his game bats. Wouldn’t a simple “X” have worked for that?
