Truthiness, not to be confused with truthsomeness or truthfulness, is rather akin to truthliness, an off flavour of truthness, but is somewhat less off. An 'l' will do that. The problem is, ls are far too common, and thus like to inject themselves into things making them ever so much stinkier, and even is have been known to turn their lacks of noses at these ls and their works.
These noses, unfortunately, have been sometimes associated with certain bouts of flying toast... naturally accompanied by flying toasters, of course. These flying toasters follow an annual migratory pattern not unlike those followed by some flocks of particularly loud butterflies, but fortunately the toasters and their toast tend to be a bit quieter. Thus the only major issue here is the fairy.
It was the fairy that gave this all away, see.
