Does the NFL own the rights to the "Who Dat" Phrase? From wwltv.com:
NEW ORLEANS - As the Saints' appearance in their first Super Bowl gets closer, the marketplace is being flooded with Saints merchandise and memorabilia as businesses are looking to cash in on the euphoria, but the NFL is cracking down on the use of their trademarks, including the iconic phrase "Who Dat."
But who really owns "Who Dat"? Does anyone? Who is a "Who Dat?" What is a "Who Dat?" Who owns the phrase, "Who Dat?"
It's a crock if ya ask me!!
