Here’s a thought, if you know you’re a mouth-breather, “Google” every word you are going to write out to see if you are about to spell it correctly.  Clearly you don’t know how to use a dictionary, and clearly you are unwilling to use a word processor to print off a professional looking sign, so pull out your iPhone and Google-check your spelling.  It’s so bad, I’ve seen COLLEGE kids turn in essays with the words “ur”, “cuz”, and “r”!  (They also don’t have any clue what constitutes a sentence.  I’ve seen strings of words without a subject/noun OR a verb masquerading as sentences.)  High schools aren’t filtering this idiots out, and the colleges aren’t filtering them out… I would hate to have to be in the position of interviewing young applicants for a job.  Well, I might have fun scanning in some of the more amusing applications and posting them to “t3h internets”, but aside from that, I’d likely end up killing.
