DNA, it's less interesting over text, but basically we were rowing on a windy day when someone's oar got caught under the water (which is easy to do when your moving quite fast), the boat begun to rock left and right, and instead of resting our oars on the water (which helps the boat balance), we all let go and grabbed onto the sides of the boat, causing us to flip over. We had to swim the boat the the edge of the river to flip it back over =.=
