The Worst Three-Legged Race

is episode 194 of the Naruto: Shippūden anime.

Synopsis
Sakura and Naruto see Kiba and Akamaru delivering some items. Sakura commented on how Naruto and Sasuke were inseparable those days and Naruto suddenly remembers the early days when they were on a mission to retrieve a golden statue, which was stolen by a band of thieves from a Feudal Princess. As Naruto and Sasuke retrieve the statue, Sakura gets taken hostage. At first, Sasuke insists on continuing the mission, but Naruto reminds him that Kakashi said those who abandon their friends are worse than scum. When they finally find Sakura and the bandits, it was at first hard for them because their hands were stuck together. However, one by one, the two quickly defeated the bandits and their leader, Jako. Although their mission was a success, the statue it self was very damaged, but Kakashi said that it could be melted down and re-casted. When Naruto complained about his hand being stuck to Sasuke's, Sakura said that it will crumble and fall apart within two or three days, much to the two's disappointment.

Trivia

 * For the second time in the series, Naruto and Sasuke accidentally kiss on the lips.
 * The scene when Sasuke wants to continue the mission without Sakura and Naruto says "shinobi who abandon their comrades are worse than scum" is a direct referral to Kakashi and Obito's conversation about Rin in the Kakashi Gaiden.
 * Jako's chakra liquid derives from Spider-Man's spider webbing, even mimicking the hand gesture Spider-Man uses when Jako activates the technique.
