In all seriousness, I write mostly non-fiction articles, book reviews, and poetry. For the first type of writing, I get ideas many places: magazines (already-written articles that inspire others, cool titles that trigger a completely different idea, and even ads sometimes), web sites (see above), books (one of my favorites is Marcia Yudkin's Writing Articles About the World Around You), and people I meet or hear about.
For ideas of books I can use for book reviews, I cruise bookstores, libraries, book catalogs, web sites, and newsletters.
For poetry, I collect things I like. I have a folder of bits and pieces: lists of words (all the words there are for the color red, for example, and a list of all the words used when doing woodworking), pictures torn from magazines, snapshots, great words with their definitions, poems I've read and really liked, words that rhyme, stray thoughts, and so on. I also have actual items I find interesting, dotted around my office:seashells, a maple tree seed, a pewter heart, a tiny pine cone...
And when I do write fiction (rare), I usually am inspired by a prompt or idea given to me by someone else.
Ideas are everywhere. The trick is to collect them, record them, and then actually use them somehow in your writing, when BIC becomes paramount.
