I recently got a catalog from a company I wasn't familiar with. Not wanting to be cheated I sent them a letter saying, "With all the fraud and misrepresentation I don't know who to trust. Send me the merchandise and if it's any good I'll send you a check."
A week later I got a letter back from the company saying, "We have the same problem you have. Send us a check. If it's any good we'll send you the merchandise."
When I was eight my Dad was taking me to see a movie. On the way there I asked him if he would buy me some gum. He said, "No, you don't need any."
After arriving at the theater and taking ours seats, Dad changed his mind. He told me it would be okay for me to have some gum and he was going to get it.
I spoke up and said, "You don't need to buy me gum anymore, Daddy. I found some under the seat."
