Lion
The lion's intimidation credentials require little elaboration. A 190-kilogram male lion possesses canines measuring up to 10 centimetres in length, retractable claws capable of disembowelling a Cape buffalo, and a roar audible from eight kilometres distant. Research from the Serengeti Behavioural Studies Programme indicates that 94% of prey animals experience immediate physiological stress responses upon detecting lion presence, including elevated cortisol levels and what scientists technically term 'the complete abandonment of dignity whilst fleeing.'
The lion need not even attack to inspire terror; its mere silhouette against the African sunset has launched a thousand nature documentaries and approximately twelve million motivational posters.
Printer
The modern office printer achieves comparable fear responses through entirely different mechanisms. A 2023 survey by the Cambridge Workplace Anxiety Research Centre found that 67% of office workers experience measurable stress increases when approaching a networked printer, with heart rates spiking an average of 12 beats per minute. The printer's intimidation arsenal includes: the ominous paper jam indicator, the perpetually low cyan warning regardless of actual ink levels, and the inexplicable ability to sense deadline urgency.
Perhaps most terrifying is the printer's capacity for selective malfunction—operating flawlessly during test prints whilst systematically failing when documents actually matter. This behaviour suggests either sophisticated artificial intelligence or genuine malevolence.
