Intentionally adding a scene/moment in a story to appease fans of the material (movie/book/tv-show). It is typically seen as a bad thing as it serves no real value to the story as a whole. Similar to the phrase, 'fan service'.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.
