Does anyone else here like to highlight lines and passages in novels that they really really like? Something that pops, or just sounds incredible? It's a habit I've been trying to get myself into lately, marking up books, and it seems to finally have caught hold on me while I was reading some more of Pnin, by Vladimir Nabokov.

Tell us something weird you do when you come across something you like, whether it be writing, TV, music, photography, whatever!
