Impossible! Celebrity Ninja Art: Money Style Jutsu!

is episode 174 of the original Naruto anime.

Synopsis
Tsunade assigned Naruto to spend the day babysitting Kunihisa, the son of Tsunade's rich friend Kunijirō. Naruto quickly found the boy very annoying from how he believed he can do and get anything he wanted simply by buying it, what he calls "Money Release Techniques". As the day progressed, Naruto helped Kunihisa begin to understand the importance of working for something through showing him a few ninja skills like kunai throwing. Unfortunately, he was later kidnapped by a couple of goons who bribed Kunihisa's own bodyguards with money Kunihisa threw away. Naruto was able to save Kunihisa but then found himself hanging over a cliff for dear life. Not wanting his first real friend to die, Kunihisa used a rope to save Naruto. They were both proud of Kunihisa's action, especially because he really tried for it.
