I was hoping some illiterate fool would jump on that, and you fulfilled my every hope, Shlomo.
"Guys" is not the subject, fool, it is "none," as in "not one," which is singular, and "guys" is only a descriptive pronoun.
"Not ONE (of you guys) can think for himself." Got it?
Eleven mistakes about grammar mistakes

9. Number 9 actually is about grammar, but what the page says is not true. It asserts that none "is always singular" for purposes of verb agreement. This just isn't true for Standard English. When none is a subject, the agreement is often plural (are, for instance). None of us are perfect, says the Reverend Dr. Chasuble in Oscar Wilde's The Importance of Being Earnest. Wilde was not intending to portray Dr. Chasuble as incapable of speaking correct English. The myth that none takes only singular agreement on the verb lives on despite many refutations. Serious handbooks of grammar and style don't represent it as ungrammatical. (Of course, the idiots Strunk and White do in their clueless book The Elements of Style; but they get almost everything wrong.)
