Oh, this was too good to pass up. Kakashi did enjoy poking fun sometimes; there was a period when he really had been a brat, after all, and sometimes it still showed. Of course, he also didn't know about Renamon's hearing, though it was obvious Jiraiya was worried about the woman overhearing them. But then, he may or may not have acted any differently if he had know how possible it was for that to happen. Especially not when he could fake innocence so well when he tried. "Other stuff?"

Said as if Kakashi, of all people, somehow didn't have a clue what Jiraiya was talking about.

"Right. A friend you have a very deep respect for." He turned the page, knowing that the sannin knew exactly what Kakashi was doing. Which was why he could continue doing it, and enjoy the sight of a legendary ninja growing increasingly flustered. Somehow he doubted many people could say they'd witnessed such a thing.

He did give Jiraiya something of a flat look, however, when the comparison to Naruto was made. "I'd like to think my technique is a bit better than his. Naruto's an impressive prankster when he puts his mind to it, but he's not subtle. If he figures certain things out, everyone in this hospital will know what's going on because he'll shout it at the top of his lungs."
