some state fan must have gotten a hold of it b/c we get the props we rightfully deserve!!:
The first use of the song at a sporting event was at Mississippi State University. The university's mascot is the Bulldog, and the university school first played the song during football games in the fall of 1999 using the version sung by Chuck Smooth. It was accompanied by the crowd singing along and the team performing a dance on the field called "The Dawg Pound Rock" just before a kickoff. Later the Southeastern Conference ruled that they could not perform the dance on the field, so the team moved it to the sidelines. Several other teams followed suit, and the song quickly became a national phenomenon.[citation needed]
In June of 2000, Greggory Greeneline, then Director of Promotions for the Seattle Mariners, was the first to play "Who Let the Dogs Out" at a Major League Baseball game. He debuted the tune as a joke for the team's backup catcher, Joe Oliver. Two days later, shortstop Alex Rodriguez requested the ditty for his batter introduction music and the song quickly became the Mariners team anthem. The Baha Men played live at Safeco Field during a Mariners game in September of 2000. The New York Mets, however, claimed that they were the first MLB team to adopt the song (ESPN.com later commented, "This is a little like scientists arguing over who discovered a deadly virus"). The Baha Men recorded a version of the song that changed the chorus to "Who let the Mets out?" and all the lyrics to reflect the team and its players, which was played at Shea Stadium throughout the Mets' 2000 postseason run, including a live performance on the Shea Stadium field before Game 4 of the 2000 World Series against the New York Yankees. The song was written by David Brody of Z100 New York and recorded by the Baha Men initially for Z100. Brody then gave the song to the Mets to play at Shea. Brody has also written songs for the 2006 and 2007 Mets. Richard Hidalgo used the original song as his entrance music while playing for the Houston Astros.
