you ain't seen nothing yet

English

From you ain't heard nothing yet, a phrase originally popularized by Al Jolson.

(colloquial) There's more where that came from; what you have seen so far is only the beginning. Used to inform the listener that they should expect further surprises, and that the speaker has only just begun doing something.

  "Ain't it a great show?" said the man. " / "'Tain't so great as 'twas last year in the Garden," she answered.  / "Yes, 'tis, too, greater," he contended; "it’s a heap higher. We’ve just come in on the main floor. Why, you ain’t seen nothing yet. This show is in stories—begins on the ground floor, where we are now, and rises up like the Washington monument."

Pascal Tréguer (2 February 2019), “Meaning and Origin of ‘you ain’t seen/heard nothing yet’”, in wordhistories.net‎^[2]: “With one exception [...], the earliest instances of you ain’t seen nothing yet are posterior to those of you ain’t heard nothing yet—which may indicate that the former phrase gained currency as an alteration of the latter.”
“The Jazz Singer”, in Wikipedia‎^[3], 8 December 2025 (last accessed): “In November 1918, during a gala concert celebrating the end of World War I, [Al] Jolson ran onstage amid the applause for the preceding performer, [...] Enrico Caruso, and exclaimed, "Folks, [you ain't heard nothin' yet]." The following year, he recorded the song "You Ain't Heard Nothin' Yet".”
