What began as a prank has grown into an outstanding act of benevolence on the part of fans of the San Francisco 49ers and Seattle Seahawks.
Supporters of both teams competing in Sunday's NFC Championship game are competing to raise more money than the other, with the funds going to a children's hospital in the rival team's home city.
According to website Deadspin, the idea was sparked when 49ers fans raised money to buy a Seattle billboard in December. As part of the prank, the additional funds were designated to benefit a local charity.
Recently, the idea escalated when an anonymous 49ers fan came forth and pledged to match each team's contribution dollar-for-dollar up to $100,000 ($200,000 total). Soon thereafter, both teams agreed to do the same, meaning for every dollar donated, $4 will go to that specified charity.
Donations by Seahawks fans will go to the UCSF Benioff Children's Hospital. Contributions from Niners fans will benefit the Seattle Children's Hospital.
As of Friday morning, gold-and-red loyalists had pledged $17,121 while their neon green foes to the north had raised $28,280.
