"Fun." 

It's completely non-obvious from his expression and tone of voice if he's being sarcastic.

"It will be!"

"Senju Tsunade is known to frequent gambling dens. Is that the fun to which you are referring?"

Jiraiya harrumphs.

"Did they teach you to make jokes since the last time I saw you?"

"Jokes are important to team bonding," he says, as seriously as he can. Which isn't very.

"All right, then." Jiraiya leans in close. "Here's one you should never tell to a Nara. What do you call a blind deer?"

"A bad joke?"

"No-eye deer. What do you call a blind deer with no legs?"

"A worse joke!"

"Still no-eye deer. What do you call a blind deer with no legs during mating season?"

"The peak of bad jokes?"

"Fucking still no-eye deer!" Jiraiya waggles his eyebrows.

"Real jokes need context. Even with, like, flat telling a joke, you gotta have a story. Otherwise you end up the only one who thinks it's funny."

"Show me how it's done, then."

"So there's a blind rabbit and a blind snake, and they're traveling in opposite directions when they meet on the road.

"'What kind of creature are you?' asks the snake.

"'Well, I don't know, because I've never seen myself,' says the rabbit. 'Maybe you can tell me.'

"So the snake crawls all over the rabbit, and says, 'You're soft and warm and have two long ears, so you must be a rabbit. Now, can you tell me what I am?'

"The rabbit agrees and feels the snake all over, and says, 'You're hard and cold and have no balls, so you must be a lawyer!'"

Jiraiya bursts out laughing.

"See! Stories!"

Jiraiya wipes his eye. "Fine, fine, you win," he says, still chuckling. "Since you're here tonight, we'll start our journey tomorrow. We'll start in the bigger towns and see if we can find any likely trails to follow."

"Alright. Just asking people if they've seen her or someone fitting her description?"

"That's the easiest way. This hunt doesn't have to be secret."

He nods. "People might be more likely to actually tell us though depending on what we say's our reason..."

"You can try experimenting. Just keep the Hokage thing on the down-low, if it gets back to her, it'll scare her off."

"She's known for gambling, right?"

"Her one weakness," Jiraiya says fondly. "She has terrible luck, though."

"Huh. I'm pretty good at cards and dice at least... But yeah probably gambling places are a good place to start?"
