By now, I have (strenuously) reached the last pages of this book/interview that I started weeks ago, and I believe that the following excerpt is the last one quoted by David Foster Wallace Alanis Morissette - You Oughta Know (OFFICIAL VIDEO) about which he says:

[...] She’s pretty, but pretty in an imperfect way, very human. There’s something in… a lot of women in magazines have a beauty that isn’t erotic at all because they don’t… because they don’t look like anyone you know. You can’t picture them putting a coin in a parking meter or eating a mortadella sandwich. But she – even though I’m smart enough to understand that partly that image is artfully constructed, that imperfection – she has a kind of sensuality that despite everything is very… I don’t know, I find her absolutely irresistible.
