A Deathday was the anniversary of a person's death, celebrated by their hologram. George McIntyre, for example, didn't survive long enough in his light form to reach this milestone. Three million years into the future, Arnold Rimmer celebrated one particular deathday with Dave Lister, The Cat, the Holly Robot and two skutters. They travelled to the surface of a bleak, rocky planetoid which nonetheless had an S3 atmosphere. On this planetoid they had a party, which included music (with Lister on guitar and skutters on keyboard), a barbecue, dancing and a lot of drinking. Lister even baked a cake for Rimmer, shaped like a technician's spanner.
