Wind-up doll jokes (or simply doll jokes) is a series of jokes in which an imagined wind-up doll of a well known person (a show business or sports celebrity or a politician) acts in a way supposedly peculiar to this person.
 An example is given in the biography of Miles Davis by John Szwed.
 Miles had a habit to walk to the back of the band after finishing his solo, which was called "turning his back on the audience" by press.
 George Crater of the "Down Beat" magazine cracked the following joke: ""Question:" What does a Miles Davis doll do if you wind it up?
 - "Answer:" It turns its back on you!"
In industrial and organizational psychology, biodata is biographical data.
 is “...factual kinds of questions about life and work experiences, as well as items involving opinions, values, beliefs, and attitudes that reflect a historical perspective.”
 Since the respondent replies to questions about themselves, there are elements of both biography and autobiography.
 The basis of biodata’s predictive abilities is the axiom that past behaviour is the best predictor of future behaviour.
 Biographical information is not expected to predict all future behaviours but it is useful in personnel selection in that it can give an indication of probable future behaviours based on an individual’s prior learning history.
 Biodata instruments (also called Biographical Information Blanks) have an advantage over personality and interest inventories in that they can capture directly the past behaviour of a person, probably the best predictor of his or her future actions.
 These measures deal with facts about the person’s life, not introspections and subjective judgements.
