Certified Rat Tickler
A new shareware game · The Bard of Bizarre, 1995 · registration $5

Doc Leo, PhD (Comedic Science), has a brand new certificate in rat tickling and no rats yet. Pin first, then tickle, or a rat will never read it as a laugh: through a night classroom, a lab full of Tesla coils, the sewers under the city and up a tower in a storm, every rat you tickle chirps at 50 kHz and joins the laughing carpet, and each door opens only for a carpet big enough. No rats are harmed. Shareware from The Sofa BBS, based on the song by The Bard of Bizarre (lyrics shaped by ChatGPT from Lewis Moten's prompts; no recording came with the song, so its music was composed for the game by Claude Opus 5.5; title, cover and certificate art drawn for the game by Claude Opus 5.5).
