An Oklahoma man donated a bit more than he bargained for to the Salvation Army last week.

The man, who declined to be identified, accidentally dropped his wife's wedding ring in one of the charity's iconic red kettles along with a handful of change in Tulsa last week.

"I had outpatient surgery at St. John's and I forgot to take [the rings] off. So at the last minute, I gave them to him and he put them in his pocket," his wife explained to local news station Fox23.

The husband didn't realize what happened until they got back home and the ring was no longer in his pocket.

Frantic, the couple called Captain Ken Chapman of the Salvation Army of Metro Tulsa asking if the ring was still with them. Chapman assured them that the kettles have a lock on them and stay locked until the counting process begins at the Salvation Army warehouse.

"So we count the kettles the next morning, find her ring, gave it to her and she gave us a $100 donation," Chapman recalled to Fox23.

The woman said she hasn't taken off her wedding ring since it was returned.

Chapman told FOX23 that strange odds and ends turn up in the kettles every year. "We have a little collection in our counting room of all the weird things we get in the kettle," he added.
