He was here, but now he's gone. Or was he ever really here? The answer, much like the meaning of life, is blowing in the wind, like a leaf on a leaf-blower.
Or maybe he was just a figment of our collective imagination, a fleeting thought in the grand tapestry of existence. But that would mean we're all just figments of each other's imagination, and that's just too meta.
We've had our share of theories, from the 'He Was Always There' hypothesis to the 'He Was Never There' theory of relativity. But the truth, much like the meaning of life, remains a mystery wrapped in an enigma, dipped in existential dread.
