Avocado
The avocado demonstrates a temporal velocity that defies conventional physics. Its journey from unripe to overripe occurs within a window so narrow that scientists have termed it the Avocado Paradox. One moment, the fruit resists all pressure; the next, it has achieved the consistency of room-temperature butter. This speed, whilst impressive, serves primarily to frustrate rather than to accomplish strategic objectives. The avocado moves through ripeness states at approximately 0.003 metres per second of cellular degradation.
Ninja
The ninja's relationship with speed is rather more practical in application. Historical records suggest trained practitioners could traverse 400 metres of difficult terrain in complete silence whilst carrying sufficient equipment to establish a small ironmongery. Modern descendants of these traditions have been clocked at speeds exceeding 35 kilometres per hour in short bursts. More significantly, the ninja's speed serves a purpose beyond mere locomotion—it facilitates the prompt completion of professional obligations before witnesses can form reliable memories.
