Trivia: User Friendly
- Defictionalization: The Vigor Assistant for the Unix VI text editor is a clone of Clippy for Microsoft Word. Some random hacker made a real Vigor Assistant.

- With only three weeks of actual new strips (in November 2010, and discounting some user-created ones) since December 2009, it has officially entered Orphaned Series territory.
