It paid for Polish fencer Adrian Castro to have his future father-in-law's approval prior to the 2016 Rio Paralympic Games.
Castro's bronze medal is likely to cost him thousands of dollars as he and his opponent had a little wager on their bout.
The father-in-law-to-be, Polish teammate and defending Paralympic champion Grzegorz Pluta, took the 15-8 defeat in his stride.
Until Castro brought up who was paying for the wedding.
"I met his daughter during a fencing training camp four years ago," the Castro said.
"She accompanied Grzegorz at that event, and everything between us started from there.
"Me and Pluta train every day together. We already fought against each other in the 2015 world championships final and I won against him.
"But today before our bout I told him 'the loser will pay for the wedding'."
From there things got awkward.
Pluta insisted Castro would be the one picking up the bill.
"Not at all, I don't agree," Pluta said.
"I lost the bronze medal, he will earn money from winning it so he has to pay now.
"Of course he has to. He has just won enough money to pay for the wedding."
