A few years ago, an Englishman called Roy Jones went on holiday to a small town near the sea in the
west of England. He was swimming in the sea one day. As he opened his mouth, his false (not real) teeth
fell out and floated (漂) away. The following year, Mr Jones returned to the same town. When he was
having dinner in a local cafe one evening, he mentioned the story of his lost teeth to the manager. The
manager looked surprised. He explained that he had found a set of false teeth on the beach last month.
Then he asked Roy Jones if he wanted to try them on. "OK," said Mr Jones. "I suppose it won't do any
harm." When the manager brought him the teeth, Mr Jones put them into the mouth, and laughed and
laughed. They were his!
In 1987, an American couple called Jane and Robert Bentley went for a picnic on a beach in
California. When they returned home, Mrs Bentley realized that she had lost her wedding ring (结婚戒指).
It wasn't expensive but it was valuable to Jane. The Bentleys drove back to the beach and searched for the
ring for three hours, but couldn't find it. A few months later, Mr Bentley went fishing off the same beach.
As he pulled a large crab (螃蟹) out of the sea, he noticed that there was something on one of its claws
(爪). It was his wife's wedding ring!
