How does he know that BURYING a RedSox item UNDER Yankee stadium wont cause a curse on the Sox? The symbolism is unmistakable.
If I were teh Yankees I would demand they dig up and repour that section of concrete.
Eventually that shirt will decompose and cause a pocket within the concrete.
Well, I'm pretty sure Bill Buckner "buried" a Cubbies batting glove under his first baseman's glove during a World Series, and even though the Sox lost the game, and the Series, they eventually were able to shake the curse.
However, the Cubs, well, maybe you do have a point about it backfiring...
