A man went into a novelty shop and saw an item that caught his fancy almost immediately. It was a stuffed rat. The man couldn't take his eyes off it, and finally asked how much it cost. The answer was "`$79.95, but if you buy it, you can't return it for any reason." The man thought this was a bit odd, but he was really taken by the stuffed rat so he bought it. As he headed down the street with the stuffed rat, several live rats started following him. He thought this was really odd, but he kept walking. Within a few blocks, he had a huge pack of rats behind him. When he got to the river, he threw the stuffed rat into the river, and all the live rats jumped into the river and drowned.
The man returned to the shop. As soon as he walked in, the owner said "I told you you couldn't return the stuffed rat!"
The man said "`No! I don't want to return it! I was wondering if you had any stuffed violists."'
