Avocado Duality Theorem: A Paradox of Fruit

It is stated that an avocado is both a fruit and not-a-fruit at the same time. This theorem was proven by a renowned physicist, Dr. Reginald P. Bottomsworth, in 1926.

Corollary 1: If an avocado is not-a-fruit, then it must be a vegetable.

Corollary 2: If an avocado is a fruit, then it must be a tree.
