It can indeed do that and many people have tried it but it doesn't make any sense to me either. Here is some evidence. http://www.school-for-champions.com/science/mpemba.htm

Because when water is somewhat cold, it adapts to cold temperatures easier and slowly takes a bit longer to actually freeze, because it's already cold. When the water is hot, it's like more of a shock and turns cold faster because it doesn't adapt as easy as if it was cold and doesn't take it's time. I hope that makes somewhat of some sense. But like you said, it doesn't always work in this situation and cold water will freeze faster than hot water. It all depends on the temperatures of the water and the temperature of the air.
An example: You have a person who is feeling cold and a person who is feeling hot. You put them both in a cold setting. The person who is already cold really doesn't notice the change and still feels comfortable whereas the person who is hot notices right away and becomes cold faster.

Warm Water Has Less Stable Particules Than Cool Water Thats Why It Cools Faster

It can happen. the hot water may have less mass because of evaporation to steam or a lower mineral content because of heating. It has nothing to do with thermal inertia or being used to being hot or cold. Try here ---

It doesn't freeze faster. Try it in your own freezer.
