"Good moaning. I was pissing by when I heard a stringe noise from your bot. Your nearest witer point is 2.3 miles ahead on the laft. The pob after the next bidge is acceptable. Do not moor below the lock in flood conditions. Obviously."
— Idris, Lockmaster AI  ·  AI canal guide inspired by Officer Crabtree from 'Allo 'Allo
