I worked with a guy that regardless of the situation, always had a story. Most of stories were so outrageous that anyone with good sense could see right through them.
Here's an example of one of his stories that I was witness to - he tells one of our suppliers that he just bought a new Harley Davidson (of some variety - went into great detail about the color, style, accessories,...etc.) and that he and his wife were going to start riding on the weekends. A few weeks later the guy comes by the office and asks him how he likes the Harley, and he replies, "What Harley - I didn't buy a Harley."
He basically said, he liked to see the look on people's face.
Kinda crazy just to think about it.
