What are some of the best urban legends you've heard of over the years?
One of the UL I've always found interesting is the "vanishing hitchhiker" one. Basically, in this one a driver picks up a hitchhiker on the street and drives them to their place of residence. They drop them off and the next day the driver finds something the hitchhiker forgot.
So when the driver goes to give it back, a person at the house tells them that the hitchhiker has been dead for a certain amount of time.
Another classic one is where a person meets somebody at a hotel and gets drugged then wakes up the next morning in a tub of ice with an organ missing.
