Something to pick can refer to a variety of items, such as bones, nits, guitars, and ORE. A BONE is a hard, calcified tissue found in the bodies of vertebrates, and is typically used for support, protection, and movement. Nits are the eggs of lice, which are small, wingless parasites that feed on the blood of humans and other animals. A guitar is a stringed musical instrument that is usually played with the fingers or a pick. ORE is a rock or mineral from which a valuable metal can be extracted.
