A simile is a figure of speech that directly compares two unlike things using "like" or "as". It can be found in movies, TV shows, commercials, literature, and songs. An example is "Float like a butterfly and sting like a bee". A metaphor is a comparison between two unlike things that does not use "like" or "as"; it uses "is" or "are" instead. Metaphors are also found across various media. An example from Shakespeare is "All the world's a stage".
