So long, and thanks for all the help. Beachgoers come to the rescue of some 30 stranded dolphins in a video racking up plenty of views on YouTube, AP reports. Dozens of shocked people at the beach near Rio de Janeiro look on as the pod suddenly beaches itself. They then race to the rescue, wading into the surf and working together to drag the mammals into deeper water. Applause is heard as the dolphins swim off. (More dolphin stories.)
