Ohio State fans, proving that even after they are dead, they are still the most annoying fans in the world.
A cousin of mine married a girl from Ohio and the wedding was in some small town there. Being that his side of the family are all from the Chicago area, during the reception someone requested "Sweet Home Chicago" from the DJ and dedicated it to all the people who made the 6 hour drive. Apparently since the "Hang on Sloopy" / OHIO chant deal started at a game against Illinois, the Ohio people decided this was a challenge being thrown at them. So while Sweet Home Chicago is still playing, they stand up and start singing "Hang on Sloopy" as loud as they can and doing the OHIO chant.
