Stadiums all over the world are known for being unique in their own ways. Wrigley Field has the ivy and the manually operated scoreboard, Qwest Field in Seattle is an acoustic masterpiece designed to make the place louder than any other, Chase Field has a hot tub for fans in centerfield, and Cowboys Stadium has Jessica Simpson jumping up and down a lot.

Kyle Field in College Station, Texas is no different as the home of the Texas A&M Aggies football team. It’s long been referred to as the home of the 12th Man, but did you know that the 12th Man isn’t a man at all? It’s not even the fans. Nope, turns out the 12th Man is just a huge pile of bat droppings.

From the WIZ OF ODDS:

The creatures have infested the upper decks of Texas A&M’s stadium, but officials don’t seem to mind. They’ve actually designated the facility a bat-friendly zone. But there are problems.

“These bats help us by eating a lot of bugs around the stadium, but unfortunately, what goes in also comes out,” athletic director Bill Byrne said.

In other words, bat guano, which has a strong smell of ammonia.

Crews spend hours each week power-washing the stadium for bat residue and have even tried a deodorizer. The primary concern is making sure bat guano doesn’t get in vendors’ food. Official have also taken steps to protect unsuspecting fans from droppings.

They also have to remind fans not to pet the bats, which can be seen flying around the stadium during night games or heard squeaking with delight as they crap all over the place during day games.

Scientist’s also believe that Kyle Field is home to the second largest bat population of any place in the United States, just behind Barbara Walters‘ vagina.
