Late for the Show, but Ready to Go! The Ultimate Secret Technique is Born!

is episode 67 of the original Naruto anime.

Synopsis
With Gaara unable to move while within his shield, and Sasuke unable to break through its defences, Sasuke decided to use his new technique: the Chidori. With it, Sasuke was able to pierce Gaara's shield, stopping his transformation, and becoming the second person to ever injure Gaara. At that moment, Kabuto Yakushi used a genjutsu to put the audience to sleep, signalling the start of the invasion of Konoha.
