Can I do one per day? Hmmm. They fly in and out so fast and a computer isn't always nearby. Notebook?
Start with this one. Two heroin junkies were stoup-sitting one day and the Yoga teacher one is telling his friend about scientific study he read that explains how one can evaluate mental health by watching someone walk.
The two friends then started analyzing passers-by. One day a girl walks by who has it all. Not only attractive, she has the perfect walk: firm, graceful, not too fast, not too slow, confident. They decided to meet her and evaluate their findings.
Both of these men are above average looks, and very above average intelligence. They introduce themselves, chat up and young woman and get to know her. Their conclusion: "She was completely crazy - and NOT in a good way!"
