Statement

Giorgio has just submitted his results on the advent of bloomsday to the renowned Journal of Scientific Hoaxes. However, his paper has been rejected by an anonymous reviewer who claimed that Giorgio used the wrong coefficients K and E for the holy sequence! Needless to say that Giorgio didn't take it too well, and started to stalk the journal's editors until he finally managed to get a picture of the supposedly "correct" holy sequence from the distance.
