You’re quoting this sentence from page 4 of Bret Easton Ellis’ disturbing masterwork, American Psycho: “[A]nd the joke is, the punch line is, it's all in this city--nowhere else, just here, it sucks...” This is the proper MLA parenthetical citation for this quote, and this is where it goes in relation to the punctuation.
What is, "[A]nd the joke is...just here, it sucks” (Ellis 4).
