The Boise Black Knights are a youth football team from Idaho. On their way home from a tournament in California Monday (which they won), they came across an overturned car. They helped the injured driver, but his wife was trapped inside the car. The players cut through her seatbelt, and decided the best way to free her would be to lift the vehicle up and help her to crawl out from underneath.
You can see a somewhat chaotic video of the rescue operation at Buzzfeed.
