I Have Just One Thing to Say

A character is giving a climactic speech expressing disgust for the actions of another character. It sounds like a stern rebuke, and builds to "I have just one thing to say!" The audience expects a final slap in the face, but instead the character says something entirely positive, revealing the speech to be a put-on.

Sometimes the "one thing to say" is, "Gotcha!"

Compare Arson, Murder, and Lifesaving.
