The Jatravartid people believe that the entire Universe was sneezed out of the nose of the being called the Great Green Arkleseizure. Due to this belief, they live in fear of the Coming of the Great White Handkerchief.
When the Jatravartids want to leave the room, they say "Did someone hear the door crystal? I bet it's Poople. Late as usual. I better go and let him in before he fills his handkerchief."
The Jatravartid people appeared in:
- The fifth episode of The Hitchhiker's Guide to the Galaxy television series.
- Fit the Fifth of The Hitchhiker's Guide to the Galaxy radio series.
- The Eoin Colfer book And Another Thing....
