The shark thrashed in the hot sun while an attentive man used a bucket to give the shark some water, reported WCVB Boston.
Stuart Smith, Chatham's harbormaster, told the AP that when he arrived at the scene, about 40 people had gathered around the shark, who appeared to be dead.
Smith and Dr. Greg Skomal, of the Division of Marine Fisheries, went into action, according to the Providence Journal. "We walked it like a big dog," Skomal said to the Journal.
The crowd on the beach cheered as the team assisted the shark back into the water. The method may not appear to be gentle, but it certainly got the shark back to where he wanted to be.
It took about an hour for rescuers to get the shark back into the water.
