Voor de knager die hem het eerst aan het lachen krijgt, heeft hij een prachtige beker laten maken: De Stenen Grapjas, ontworpen door een beroemde kunstenaar. Het is zo\u2019n mooie prijs dat zelfs de beroemdste grappenmakers van de hele oertijd meedoen! Dan wordt de beker ineens gestolen, en kan er helemaal niemand meer lachen\u2026 Wat nu?",
