It was a joke? It comes across like you pointing out someone missing evidence and being wrong. Obviously you used the word "funny" but that's not usually a word that goes in a joke.
Nevertheless the joke is already dead. There's no reason not to explain.

Explaining a joke is like dissecting a frog, you learn more but you kill it in the process.
