The first video I've provided is hilarious but sometimes truth's stranger than fiction. The video's about about a woman complaining that she continues to date the same kind of man. The author explains the guy simply shape shifts into her next date to create the illusion it's a new man she's seeing.
"Shapeshifting is a common theme in mythology and folklore as well as in science fiction and fantasy. In its broadest sense, it is when a being has the ability to alter its physical appearance. The transformation may be purposeful or not, depending on whether it has been the subject of a curse or spell. In some folklore, once the shapeshifter has become transformed, it becomes progressively more difficult for it to return to its original form." - Wikipedia
This video is meant to be humorous but sometimes truth can be stranger then fiction.
