Anatidaephobia

Anatidaephobia is a branch of Ornithophobia; the fear of ducks. According to Wikipedia, Anatidaephobia is the fear of somewhere, somehow, a duck is watching you. This was first a joke phobia in a one-panel comic called The Far Side by artist Gary Larson where a man in his office sees a duck out his window all this time, but it turned into an actual developable phobia. Early captions for this comic do not mention the phobia, (Raymond could feel it. The duck was watching him again.) and if it were not for the caption change, this phobia may not have come to be.
