Amusement is the state of experiencing humorous and usually entertaining events or situations, and is associated with enjoyment, happiness, laughter and pleasure. The word "Amuse" is so named from the opposite of "Muse" -to learn or to think. Current studies have not yet reached consensus on the exact purpose of amusement, though theories have been advanced in the fields of psychology, psychiatry and sociology.
