For further spelling confusion try this verse:
An Orthographic Lament
If an S and an I and an O and a U With an X at the end spell Su; And an E and a Y and an E spell I, Pray what is a speller to do? Then, if also an S and an I and a G And an HED spell side, There's nothing much left for a speller to do But to go commit siouxeyesighed.
