NBC Sports Chicago trolled Buffalo Bills fans, but the Bills Mafia responded in the classiest way. NBC Sports Chicago ran a video feature on Twitter that asked, "Who are Bills Mafia?" The video featured clips of fans slamming one another through tables and called the Bills Mafia the "the laughing stock of the league." The Bills Mafia turned a negative into a positive. One Bills fan with the Twitter handle @COBillsFan decided to show that the Bills Mafia was much more than table slamming when he made a donation to the Bear Necessities Pediatric Cancer Foundation. So far, the Bills Mafia has raised over $10,000.
