On December 5, 2006, Universal Press Syndicate issued a press release stating that his strip, "FoxTrot", would turn into a Sunday-only strip. Amend stated that he wants to continue doing the strip, but at a less hurried pace. This news was followed by several weeks of the characters discussing a "cartoonist" semi-retiring to Sundays only, and what methods he would use to phase out the daily strips. The last daily FoxTrot cartoon was printed on December 30, 2006. Amend also sometimes does guest strips for webcomics such as Scott Kurtz's PvP, Mike Krahulik and Jerry Holkins's Penny Arcade, and Randall Munroe's XKCD.
