For hundreds of years, the people of a Scottish town believed that a dinosaur-like strange creature(生物) lived in a nearby lake called Loch Ness. Many said they saw the creature, but no one could prove it was real.

In 1934, a London doctor, Robert Kenneth Wilson, gave a newspaper a photo of the strange creature. He took the picture, he said, when he suddenly saw the animal in the lake one morning. The news traveled around the world. People came from everywhere to see this creature, now called the “Loch Ness Monster.” Then, in 1993, a man named Christian Spurning surprised everyone. He said the photo of the “Loch Ness Monster” was a lie. He and some friends created the famous picture themselves, and then Wilson gave it to the newspaper as a practical joke.

Today, tricks and jokes like this are common, and many are spread using e-mails. Some can be funny, but others can cause trouble. In August 2000, an e-mail was sent from a large British supermarket chain(连锁店)---Safeway---to thousands of its shoppers. It said, “Store prices are going to increase 25 percent. If you don’t like this, go to another store.” It was signed(签名), “the Safeway Team.” The e-mail worried many of Safeway’s shoppers and caused big problems for the supermarket. Later, Safeway discovered what happened. Someone broke into the company’s website and sent the cheating e-mail.

Not all tricks are as bad as this one. Some make us laugh, and others surprise us. In the end, they all show us that seeing is not always believing.
