No, this isn't a joke.
The Flyers have installed a "rage room" at Wells Fargo Center for fans to use during games.
"The rage room-style space allows fans and guests a stress-relieving outlet amid all of the game action," the Flyers said in a press release. "Through scheduled sessions that can be reserved in advance, participants wearing protective gear can smash, break, and unleash their rage upon everyday items like televisions and dishes using bats, sledgehammers, and more. Some of the items that can be disassembled might even bear the logo of an opposing team."
"The concept is definitely one-of-a-kind and non-traditional," said Valerie Camillo, President of Business Operations of the Flyers Flyers and the Wells Fargo Center.
