Uploader Tigran Kapinos took this clip of a lifeguard at Virginia Beach tentatively jogging to the sea to tend to a dangerous situation. When he reaches the water, the lifeguard slips on his flippers and makes an heroic dive into the sea. However, after a few strokes the lifeguard is crawling to his feet having hit a bay of sand. He then trips over before blowing his whistle to warn endangered swimmers. Credit:YouTube/TigranKapinos.
