i believe that is episode three of the original Naruto not Naruto shippuden..... that is the episode where Naruto pawned sasuke and transformed himself to look like sasuke so he could get some one on one time with sakura cause he likes her but she likes sasuke
It was Episode 3: Sasuke and Sakura, Friend o Foe? It is when Naruto meets his new teamates, Sasuke and Sakura. Naruto Transforms into Sasuke to get Sakura to baciare him, but ends up having to go to the bathroom because of his spoiled latte
