What language strategy that incorporates humor involves telling a story with an unexpected twist at the end?

The language strategy that involves telling a story with an unexpected twist at the end, while incorporating humor, aligns closely with the concept of wit. Wit is characterized by its cleverness and often involves a sharp, humorous remark or insight that surprises the audience, leading to amusement.

An anecdote, while it can be humorous, is simply a short and interesting story about a real incident or person, and does not necessarily involve a twist or a punchline. Satire employs humor, irony, or exaggeration to criticize or mock, usually addressing social or political issues, but it may not include a story format with a surprise ending. Parody mimics or exaggerates the style of a particular genre or work for comedic effect, but it does not inherently involve storytelling or an unexpected conclusion.

Thus, the cleverness and surprise element of wit make it the most fitting choice for a strategy that involves telling a story with an unexpected twist at the end.
