This man had many enemies, and when they found out about his phobia they began to taunt him with bananas. But it wasn't only his enemies who taunted him with bananas. Sometimes his enemies would hire banana hit men to taunt him. Everywhere this man would go, he'd see strangers walking around with bananas. Sometimes they'd be eating them, and sometimes they would just carry them around, menacingly. And if that weren't enough, he noticed that many new fruit stands were opening near his home and place of work, all prominently displaying their bananas, clearly in order to make his life a living hell.
It's not as if the man lacked perspective, though. I'm just afraid of bananas, he thought. There are plenty of real nuts out there.
