There was a man, who was morbidly afraid. Specifically, he was terrified of making mistakes of any kind. He never talked to anyone, for fear of an awkward silence in the conversation. He never dated, because he was afraid of rejection. He never brushed his teeth, because he was a fraid (deliberate typo) of poking himself. With a toothbrush. He never ate because he was afraid of staining his clothes. One day, shortly before his death, he created an invention. It was a new type of keyboard. You see. He was afraid of making typos. It only had one letter, "f." They sold it to the general public.
