VICTOR, N.Y. At home, he's an unassuming father and an obsessive Bills fan.
"An obsession, I wouldn't call it an obsession,” said Joe Hart. “I'd just call it being a fan."
But there's more to Joe Hart than meets the eye. They call him Superfan, and he's here to save the party.
"There's the Superfan with his mere mortals," said Hart.
Hart is a relative newbie at the Ralph. He just got his season tickets three years ago but he's already making a name for himself.
"Everyone in my section, I sit in 124 and they all know who I am,” said Hart. “Everytime I walk down the aisle they're all high fiving me. We get wild down there in 124, absolutely."
A lot of it has to do with how he dresses.
"We started to go to the games and I decided to get a costume together,” said Hart. “We thought it would be a great idea."
It centers around the mask.
"It's got the Bills logo here and it's got the Bills logo on the back."
It's a real Lucha Libre wrestling mask.
"The second year I had actually lost it,” said Hart. “So over the offseason I had to get one ordered and I found a website in El Salvador."
But the costume isn't the only reason he and his pals get noticed.
"We get wild,” said Hart. “We have a great time and that's what they like. When the Superfan's crazy, that's what they like."
But even in costume, Hart's a father first. Sometimes he brings the pint-sized Superfans along.
"The kids like it,” said Hart. “They dress up. I brought them to a preseason game this year and they have their belts and masks and their Stevie jerseys."
As they get older he hopes they'll share his enthusiasm even more.
"If my son wanted to d o that or my daughter wanted to do that it would be awesome,” said Hart. “We could go together. I'll be 50, 60 years old still going in the costume."
