Rule question

[joemoore]

This has happens all the time. The pitcher ties his shoes and secretly gets some white tape on his wrist. When he pitches, the batters don't swing because they see the tape, the runners are diving back to their bases.

I hear that white (I mean really white) pitchers are being recruited. They go to the beach to get all tan, but they wear a watch. Then when they pitch without a watch their skin decoys all the batters and runners.

What's that patch of white on his wrist? Could it be the ball? Oh no!
