chained_bear "...he brought in the enormous cuttlefish, borne high on a silver charger, cried 'Make a lane, mates,'... and advanced to set it down... But his right foot trod on the pennant's end, his left caught in its substance, and down he came, flooding his captain with melted butter... and flinging the cuttlefish to the deck.
"'That was a lapsus calami indeed,' observed Stephen."
