Why Would I Lie? (1980)

Cletus is a compulsive liar. He prefers the term 'fabrication' to lie though. When Cletus becomes a social worker he's assigned the case of a boy called Jorge (with a 'J') who was taken from his mother. Cletus sets out to reunite Jorge with his mother, but to do so he has to fabricate many a story to keep Jorge from being adopted. In search of the mother, Cletus meets and falls in love with a women's advice councillor.
