If this isn't a previously well-described law then it should be.
Whenever thou laughest at another's spelling or grammar, the spelling thou usest in doing so shall be found to be equally dodgy.
Take this, from the Independent, for example:
Thirteen out of 20 world class university websites analysed by Australian spelling software Spellr.us were found to have miss-spellings of the word ‘university’.
...
Despite representing one of the UK’s oldest and best educational institutions Cambridge’s website was found to have miss-spelled the word ‘service’ in one of its navigational bars.
Miss Spelling must be very upset.
