"Hug" is the 11th episode of the first season of the WB original series, Smallville. The episode was written by Doris Egan and was directed by Chris Long. It originally aired on February 5, 2002.
Perhaps one of the oldest and most important forms of affection is the hug. Its roots can be traced to many thousands of years ago. It is not a feature peculiar to human beings alone as there are many species of animals, which engage in a similar exchange of warmth.
