Panda
The giant panda operates on a schedule determined entirely by its own inscrutable preferences. Visitors to panda enclosures report that the animals spend approximately 55% of their time sleeping, 45% eating bamboo, and 0% acknowledging the existence of paying guests. Breeding programmes have discovered that female pandas are fertile for precisely 24-72 hours annually, during which the male must somehow be persuaded to take interest. The species' approach to reliability can best be described as 'aggressively indifferent'. Yet within these parameters, the panda is utterly consistent: consistently unavailable, consistently horizontal, consistently charming despite offering nothing.

VERDICT
Both entities specialise in disappointment, yet the panda achieves a higher form of unreliability. It has never promised functionality, merely existence. The printer's betrayal is deeper because it occasionally works, creating false hope that the panda has the wisdom never to inspire.
