Once I went into a shop and bought some purple elephants. This particular shop specialises in selling purple elephants to people who collect purple elephants. And I am definately a purple elephants collector! I just love purple elephants and have many in my bedroom. My friends laugh at my collection of purple elephants, but I don't care.

Once I started collecting purple elephants I just couldn't stop. I think purple elephants just ROCK!

I have a friend who prefers green elephants, but they do nothing for me. It must be purple elephants and nothing else
