Bob Passovoy is active in science fiction fandom and filk music. He is credited with coining the 5-2-1 rule of convention-going, defining the amount of sleep, food, and showers convention attendees should include each day. Passovoy is also a founding member of the Dorsai Irregulars, a group which provides security to conventions, and serves as the organization's Corporate Agent.
At science fiction conventions, Passovoy often acts as an auctioneer and has helped create the style known in science fiction circles as Midwest style, which includes a lot of humorous schtick as well as straight auctioneering.
Anne and Bob Passovoy were inducted into the Filk Hall of Fame in 2008.
