Arong's post is littered with grammatical and spelling errors. Even if Arong was being ironic, which is highly doubtful, the effect is somewhat lost in his sea of incoherence.
Gillver, however, has typed with correct punctuation, capitalisation and grammar throughout. He knows where apostrophes...
I'm amazed I need to spell it out.
Gilliver stuck a "should of" in his post as a deliberate joke. He put it there as an ironic joke to take the piss out of the originator of this thread.
Now Everest and you are haranguing him for a grammatical error.
You are either suffering an irony bypass...
