Clayton and Brittany Cook were posing for some picturesque wedding photos by a river in in Ontario, Canada when a boy nearby fell into the water.
Without even taking off his suit jacket, Clayton jumped into the river and rescued the child, and it was all caught by their wedding photographer.
Brittany at first thought it was a joke, but wasn't surprised by her husband's heroics, telling the BBC, "That's Clay to me. It's something he would just instinctively do."
As for the boy, he was shaken up but unharmed and went off with an older sibling.
