Classy, real classy for a cowboys fan. Thanks a lot. Not!
Hey, that song has been around for a long time. As is the ribbing that goes between Dallas-Washington since almost day one of the Cowboys entering the NFL. BTW Clinton Murchison owned the rights to the song and that lead to the war between Cowboys-Deadskins franchises complete with the infamous chicken attack among other shenanigans.
If you don't want to be ribbed, start rooting for the Dolphins or Raiders!
