The fly hasn’t eaten for an entire day and it’s starving. Finally, it finds a pile of edible gelatinous goo. It begins eating when suddenly a green light appears, and the food, which was far from delicious a moment ago, becomes irresistibly sweet. The fly, excited by the sudden improvement, eats with increased vigor. But its enthusiasm quickly wanes when the green light disappears and the flavour of the food reverts to its original blandness.
