Since its publication 25 years ago, Bret Easton Ellis' American Psycho has remained one of the most graphic novels ever written. Its brutal depiction of wealthy Wall Street banker Patrick Bateman, who relentlessly butchers and tortures everyone who comes across his path, continues to shock and thrill readers.

Told in the first person, American Psycho shocked the world when it was first published in 1991, thanks in large part to its explicit dialogue. For the controversial book's 25th anniversary this month, we revisit Bateman's most spine-tingling quotes.
