Brain Teasers

I was trying to think of a post to write and decided to write one about brain teasers. If you have the answers, you can email them to me at julander@cox.net or leave a comment on this post.

1. I am a man. If Jason's son is my sons father, what relationship am I to Jason?

2. A black dog stands in the middle of an intersection painted black. None of the street lights are working due to a power failure caused by a local storm. A car with two broken headlights drives toward the dog, but turns in time to avoid hitting him. Without moonlight, how could the driver have seen the dog in time?

3. In Duncan's cottage, where the temperature is below freezing, there was a newspaper, a fireplace, some kindling, and a kerosene lamp. What should he light first?

4. Professor Phil was motoring along leisurely when he realized he was late for a lecture. He took the next corner on two wheels right in front of a policeman. The policeman made no effort to pull him over. How could Professor Phil get away with such driving habits?

5. Forward I'm heavy, backwards I'm not. What am I?
