"No sleep? That must be tiring!" he said first, then quickly realized that he'd inadvertently made a joke out of that and lifted his hands in shock. "Ah, that was a joke! But not a Skull Joke! Yohohoho! But I guess Skull Jokes won't work anymore since I'm not a skeleton.... but that's all right! I can just make new ones! Yohohoho!"

The returned echo of fifty years caught in his ears (which he had as well!) and stopped his laughter a moment. It was a little different hearing someone else say it. Brook knew just how long it had been - a whole half-century since he and his crew had died in that god-forsaken Florian Triangle. But now others knew, or well, did know where he was from. Luffy didn't exactly know the story, not yet, but he would. Everyone would. And then it wouldn't be something only he had to know and remember. "Hmmm, the years would be... let's see..." Brook mumbled a little, raising his lanky fingers for a little counting math. How old was he really? "Eighty-... eight about-- yes, eighty-eight! That's how old I'd be! Though," he looked down at his hands, "Physically I'd be the age I died at. Forty-one then! I age well don't I?!" he asked suddenly.

Then his mouth fell. "What kind of musician would I be if I couldn't sing?!" 'Could he sing'? Really! "Any pirate should be able to sing, you know! That's a merry-making standard! Yohohoho!"
