When You Curse Someone, You Dig Your Own Grave

is episode 87 of the Naruto: Shippūden anime.

Synopsis
Sakura and Sai leave to help Shikamaru. Hidan attempts to break out of Shikamaru's weakened Shadow Imitation Technique on him, but Shikamaru pulls the explosive tags onto Hidan's body. Shikamaru then opens a trap hole that he had prepared, and reveals his plan to bury Hidan beneath the Nara family woods. He has a vision of Asuma entrusting his "will of fire" to him, and then throws his lighter to ignite the tags on Hidan, which explode and dismember the latter. Meanwhile, Naruto prepares the new jutsu that he had been developing, Wind Release: Rasenshuriken.
