Packers/Bears team hatred over the years...

you want to really know how much the team hatred is between the Bears and Packers... in the 1920's,a Bears' player broke the nose of the Packers' starting center,when he punched him... two things happened in 1985:William "the Refrigerator" Perry scored a touchdown rushing the ball(at Soldier Field),and caught a touchdown pass(at Lambeau Field),and someone put horse manure in the Bears' locker room,before the game,at Lambeau Field,that year... talk about team hatred....
