We were dating for a few years.  On one of our trips to the White Moutains in New Hampshire (Jackson to be more specific), we were walking by a covered bridge.  After talking on the bridge for a few moments, she was telling me about a story that her cousin lost her hat in a river.  Her boyfriend jumped in a river to get it when his toupe fell off and he tried to hold it on but it was ruined.  Right after that, I asked her to marry me.
After 5 years of marriage, we still go to the bridge every year and joke about the "toupe story".  And no, I don't have a toupe......yet.
