Spotted Saturday at the New York City Nike Outlet Store by Late Show with David Letterman producer Eric Stangel.
Stangel asked a store employee about the shirts. He said: “We’ve been taking them down, but somehow they keep ending up back on the rack.”
UPDATE: To clarify, these shirts were created before the Boston Marathon attack. They are apparently referring to dramatic wins by the New York Yankees over the Boston Red Sox in 1978 and 2006.
