My son had those Hulk gloves, too. When he was eight years-old.
Imagine that guy walking into a football stadium dressed like that in the 50s-60s? What a friggin a$$ kicking. Other than sporting Mexican garb to mock our QB and that culture, I never understand folks getting dressed up like that. Stupid.
Tailgating is fun. Alcohol, food, games, music, (some) women. It makes going an Event not just some regular game. True, there are a bunch of idiots out there. But the mature, level-headed fans, out number the morons.
The face paint and all of that, I understand. Some of these guys lead boring lives and coming to a game where they can "rebel" like that makes them enjoy the game much more. Others, use the face paint to cover their real faces because chances are they will be hugging the porta-poty later on.
Regardless, tailgating is the ONLY reason I pay for a game. If I wanted to be quiet and cheer for my team using my "inner voice"...I would be a golf fan.
What they should do, is seperate the lot to have a family side and have a ...not so family side. Just my opinion.
