UW-Athletics announced Friday afternoon that if the vulgar chants aren't heard Saturday, two student ticket holders will receive trip to bowl game this year.

Here's an excerpt of the email sent out Friday afternoon:

If the so-called "ES-FU" chant is not heard Saturday at the Indiana game (from the time the gates open until the 5th Quarter is over), we will randomly select two student football season ticket holders to be the recipients of a trip (transportation, three nights lodging and game tickets included) to our football team's bowl game this year. This offer is in effect for the remaining home games this season. In other words, if the chant stops for the rest of the season, six individuals will have free trips to the bowl game.

Director of Athletics at the University of Wisconsin Barry Alvarez and UW Head Football coach Bret Bielema have sent letter to UW Student Season Ticket Holders asking them to end vulgar cheers and chants.

Here is a portion of the letter:

We are asking you to end the vulgar chants at our home football games. We'd like to share some of the correspondence we receive throughout the football season from not only visiting fans, but your fellow Badger fans as well:

"This past Saturday, my son and I attended our first Badger game at Camp Randall. All in all, it was great fun; however, one thing surprised and disturbed me. During the course of the game, the student body was led in a very obscene cheering consisting of echoing "Eat s---" and "F--- you." I was pretty appalled considering that not all the spectators were 18 years or older. It was not the sort of thing children should be hearing."

"I recorded the game at home. You can hear the students chat "You f***ed up" when another player commits a penalty. I can't imagine that's the image we want for UW."

"The vulgar profanity the students chant back and forth to one another for amusement inside the stadium during the game is simply pathetic. I expected much more from the Wisconsin program."

"I was absolutely appalled by your students. I have been to about 15 other campuses, and I have never experience worse students than I did at Wisconsin. In all of the venues I've been to, I've never dealt with students with less class than I did at your school."

These are just a small sample. There are many more. We think you are more creative than this. We believe you want to represent yourselves, your university and the football program in a classier manner than this. We believe you can have a great time at Camp Randall without chanting four-letter words.

NOTE from NBC15: We'd like to know your thoughts on this letter. Do you think vulgar language is a problem at UW games? Leave your comments in the comment section below.
