No segundo livro do Guia do Mochileiro das Galáxias, os contratados foram instruídos a não instalar um teleportador em um navio que seria enviado ao sol. Eles fizeram de qualquer maneira e colocaram no 5x o preço em "Sndry, explns". na conta.
... the foreman had explained that the accountant could go and boil his head and the accountant had explained to the foreman that the thing approaching him rapidly from his left was a knuckle sandwich. After the explanations had been concluded, work was discontinued on the teleport which subsequently passed unnoticed on the invoice as “Sund, explns.” at five times the price.
Entendo que a primeira parte é "diversa", mas o que é "explns"?
