Any good completed fanfiction about Naruto and Jiraiya's adventures during the time skip?

My older brother has been asking me for a good fanfiction about Naruto and Jiraiya's time together when they were training. I just need some suggestions of any that are completed and have anything to do with "The Adventures of Naruto and Jiraiya" basically. They can be a whole story or just little funny parody type stories anything like that is fine.
