If thou art not singing an original composition in Operatic tenor in thine shower, and if thou relaxeth not thy mind of all lesser earthly concerns during the sacred time of the bath, to focus the pure cosmic energy of thy will into the chaste and sublime art of singing therein...
Thou art doing it inexcusably wrong! Sacrilege, I say, to have any mundane, banal thoughts pollute the sanctity of the mind in the bath! Sacrilege, I deem, for there to be anything else that steers thee in the bath, other than the wondrous, soulful journey of song, of music of the mind and harmony of the voice!
Begone, O proponents of heresy! In the name of bathroom singers everywhere, I deem thee desecrators of art! Away with thee, ye worldly ones, and keep thine mundane thoughts to thyself, outside the sacred shower, and bring them not within!
