Unsure of how to put together complex sentence containg words of" defeat, graciously"

Question

I have seen many translations for some of he words "defeat and graciously". I am not sure how to say the following complex sentence:

You are not funny. I am not crazy. Learn how to accept defeat graciously. This will not be the last time.

Answer 1

First of all, you don't have a complex sentence; you have four simple sentences. Do you want to combine them into a single sentence? They don't really fit together.

No eres/estás muy gracioso. (Depending on whether you mean all the time or just right now)
No soy/estoy loco. (ditto)
Aprende a aceptar las derrotas gentilmente.
ÿsta no será la última vez.

Answer 2

Thanks for your response. I want them to be four seperate sentences. I am trying to speak jokingly wiith someone and I guess that's the issue.
