Never happened. If it did, happens everywhere.Funny you mention a Purdue game at Kinnick as if maybe hokroaches are well behaved in that game. I happened to be at the 2015 Purdue at Iowa game (Iowa won big) and Iowa fans were asshats to Purdue fans/cheerleaders. It had snowed the night before so there was a ton of wet heavy snow still in the stands. Their loser fans kept throwing snowballs at the team and cheerleaders to the point that the PA announcer had to tell people to stop (they didn't). A Purdue cheerleader got pelted in the face by a snowball. That hokroach fan not only wasn't kicked out but was celebrated by the others in the stands.
