Team 7 was riding in a truck with Kakashi driving (don't ask). When they had finally made it to their destination, Naruto had almost died of boredom.
"Finally!" Naruto yelled, "Let's get this dumb D-rank over already!" Needless to say…he got punched, and then he saw the massive staircase and looked at his sensei.
Kakashi shrugged, "The piano must go up," and with that he drove away.
Naruto, Sasuke, and Sakura decided to push it up, made it halfway to the top, then the piano fell, and Sakura gave up. The boys looked at each other and sighed.
"The piano must go up," Naruto shrugged, uncannily resembling Kakashi.
The boys started pushing/pulling the piano, with Naruto pulling and Sasuke pushing. They made it a quarter of the way, and then…the piano fell on Sasuke, pushing him down, then he gave up.
Naruto went down, looked at the SasuSaku duo, looked at the stairs and said determinedly, "The piano must go up!"
He tried tying it around him, but only made it two steps up. When he looked down, Sasuke and Sakura were eating dango, still he kept on, this time pushing. An hour later he had finally made it up, then Hinata Hyuga came out and smiled.
When Kakashi came back he saw Sasuke and Sakura asleep and Naruto coming down the stairs with a lipstick mark on his cheek. On the way back Naruto was in the truck with Kakashi, and Sasuke and Sakura were in the back, again.
When Naruto went back in time, however, he was smarter and used shadow clones…and came back with more than just one lipstick mark.
