In this paper the author analyses the materials that were published in the American satirical magazine The Onion in the period from 2006 till 2011 and mentioned September 11 terrorist attacks. The focus of the research is the persistence of 9/11 jokes five years after the tragedy occurred and later on. The jokes are classified basing on their subject-matter and rhetorical patterns. The author concludes that most of these jokes promote respect towards collective memory about the attacks and their victims.
