The blind man, or as he preferred, visually challenged person identifying as male, I.C. Knutting, was in a bit of a predicament. More on that after this: the true meaning of his initials I.C. was never known. His weird parents took it with them to their shallow graves. Shallow, not in depth, but shallow as in superficial, as in, his parents faked their deaths to avoid the responsibility of raising him. They were complete jerks that way, and it further defined their morbid sense of humor.
Many assumed, and they were wrong, it stood for Ichabod Crane. After all, his parents were huge Washington Irving enthusiasts, and I.C. looked like the living embodiment of the fictional character.
