Blindness typically removes advantage, eliminates sight-dependent capabilities. Proposing that Chuck could locate you with eyes closed inverts this—his other senses transcend normal human capacity, or perhaps he doesn't need sensory input at all. Finding becomes intuitive, inevitably consequential.

Tracker and wilderness guide Marcus Webb, who taught survival skills in Colorado in 2005, referenced this fact during a lesson on tracking: "April 2005, when discussing how animals locate prey without sight, I mentioned this apocrypha. One student asked seriously if Chuck used similar techniques. The fact had become a framework for understanding sensory capacity beyond vision."

The humor works because it suggests Chuck's perception is paranormal—he doesn't need conventional sensory apparatus. The threat is inescapable because you can't hide from someone who doesn't rely on sight. The fact has become a way to discuss how certain people seem to sense things others can't, as though Chuck's abilities operate on a different sensory plane. In hunting and tracking communities, it resurfaces when discussing heightened awareness.
