It conceived it while half asleep in the morning, yearning to

Examples of Fantabulary Theory situations:
You want a slab of chocolate
cake. Unfortunately, chocolate
cake will make you
fat.
You want to drink soda. Water's so much better for you.
You want to punch Lucas in the face. But that will lead to suspension from school, firing from a job, lawsuits, and various other negative effects.
