Improper Benefits Bowl 

College football game played on Sep. 17, 2011 between THE Ohio State Buckeyes and the Miami Hurricanes (also a rematch of the 2002 National Championship game). Noteworthy because both programs are currently under serious NCAA investigation for receiving several "improper benefits" such as cash and discount tattoos in exchange for team memorabilia (OSU), and yacht cruises and sex parties (UM), all widely covered in the mainstream media.

ESPN presents "The Improper Benefits Bowl" sponsored by Fine Line Ink Tattoos and the South Beach Yacht Club.
