A comedy is entertainment consisting of jokes and satire, intended to make an audience laugh. For ancient Greeks and Romans a comedy was a stage-play with a happy ending. In the Middle Ages, the term expanded to include narrative poems with happy endings and a lighter tone. In this sense Dante used the term in the title of his poem, La Divina Commedia.A how-to is an informal, often short, description of how to accomplish a specific task. A how-to is usually meant to help non-experts, may leave out details that are only important to experts, and may also be greatly simplified from an overall discussion of the topic.
