BTW, this may have been mentioned before, but I think it's worth mentioning again...
While I too have a dislike for the Bears, the pic in your avatar is giving the middle finger salute to Soldier field, which is named such as a memorial to U.S. soldiers who have died in combat. I get the picture, but some people may take it the wrong way and take offense to it (kinda like you've taken the good-natured ribbing of your OP).
