The idiom last hurrah refers to a final act, achievement or effort, but the context here describes it as the first opportunity before they bow out gracefully.
Context: I'm about to be on helen's show,I say, and then I explain how it's my first opportunity, and then I 'll bow out gracefully.
Hypothesis: I'm about to be on helen's show,I say, and then I explain how it's my last hurrah, and then I 'll bow out gracefully.

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
