Purchase a hatchet and 7 copies of your most loathed newspaper. Stack the newspapers and roll them together, fastening the resulting cake roll with elastic bands. Plate and freeze. In the morning, slice off a dessert-sized portion for melting next to your bowl of cereal and cup of black coffee. If, after breakfast, you cannot deduce at least one thing you hate about the newspaper from the soggy mush, its contents will determine your poem's subject matter. Otherwise, dump it in the trash and try the next slice tomorrow.
Suppose you spot the word "politics" upside down drooping over the plate onto the table and the name "Tibetan Mastiff" crossed with the word "court" in the middle where ink should be pooling.

Record using tape or laptop microphone.
