The Callistover, also known as 4/20 to some, is the day of celebration of the arrival of Callisto and the annexation of Sapphire's TeamSpeak3, converting it to the People's Republic of Callisto. Whenever Callisto is present on the Callistover, it becomes a Day of Happening, where usually a Q&A session is held with Callisto. The very first Callistover on April 20th of 2013 was a Day of Happening and the dialogue is recorded in the Callisto Dialogues which includes Callisto's recital of I'm not Callisto.
