2 Works in Hyuuga Hiashi/Uchiha Mikoto
When the Konoha Twelve's parents decide time travel sounds like a nice idea, due to the drunken blabber of one Minato Namikaze, they travel to the future to meet their yet to be conceived children(well, minus Itachi and Hana who are already born) and do what parents do best: Embarrass their children.
However, upon coming to the future, the previous round of Konoha's Twelve(*cough*Thirteen*cough*) are horrified at the state of things and decide to fix the shit fest that is the future.
(Meanwhile the parents, in a stellar display of reasoning, bring along a sad-drunk Orochimaru and a suffering thirteen year old Kakashi - both of which are confused at what they've become.)
When Kyuubi was extracted from Uzumaki Naruto, it was the Nidaime Hokage that came up with an unconventional solution. An experimental reincarnation jutsu on Namikaze Minato and a one-way trip, with his Kurama, to the past.
