Gotta See! Gotta Know! Kakashi-Sensei's True Face!

is episode 101 and an omake episode of the original Naruto anime. The episode was filled with inconsistencies to the rest of the series, as the episode itself was not meant to be taken seriously.

Synopsis
Naruto had started the idea of finding out what was under Kakashi's mask. Sakura agreed, at first, Sasuke didn't agree, but Naruto convinced Sasuke by saying maybe he had lips like a blimp and buckteeth.

Naruto starts the idea in Ichiraku Ramen Bar, Naruto, Sasuke, and Sakura treated Kakashi to some miso ramen, in the hopes that they would get to see his face once he removed his mask to eat. As Kakashi gets his chopsticks, the team was all looking at Kakashi concentrically. Just as he was about to take off his mask, Team 10 (without Asuma) appeared, which blocked the others' view of Kakashi's face. After the short arguments with the team, Kakashi had already finished his miso ramen, realising how fast their sensei ate the ramen. Naruto noticed that Teuchi and Ayame were both awestruck at the sight of Kakashi's face (suggesting that Kakashi has a handsome face), which made the team even more curious.

Sasuke had come up with the idea of tailing him. He stops at the place near bulletin their hiding. As he ran saying "he will reserve his ticket", he left, as the team followed him, he suddenly vanishes. They're surprised. Sasuke decided that they should try tailing him again one by one. Naruto failed to do his turn because Kakashi suddenly left. Sakura was fooled in the memorial, dressing a scarecrow like Kakashi, and lastly, Sasuke also failed.

Team 7 were going out on a mission to help out on a farm. As they headed out of Konoha, three Rogue Ninja were spying on them. Aniki, the leader of the three, wanted to kill Kakashi as revenge. When his team-mate said that he had forgotten why, he recounted how, three years ago, he proposed to marry him to a beautiful woman. After a failed attempt to propose to the woman, Kakashi came out of a bush, saying that, if the woman had said no, then don't bother her. The Moya Triad became annoyed and attacked him. Kakashi made quick work of the three, and they were shown tied up, dangling between two trees. Kakashi took the girl back to her village.. To avoid getting beaten up by Kakashi again, the leader decided to use another method to kill him.

The team decided to stop at a motel for a break. Greeted by a lady, the team prepared to eat lunch. The lady who had served them turned out to be Aniki in disguise, who snickered to himself about how he had added a toxin to their food which would give the eater endless and uncontrollable hiccups, thus killing the person. Sasuke, Sakura, and Naruto told Kakashi to go ahead and eat first (so they could have him take off his mask again to eat). Kakashi told them that he was on a diet. Naruto threw a kettle of hot tea at Kakashi (a method of taking off his mask), claiming that his hand had slipped. Kakashi threw the table up immediately, causing all the food to drop to the floor and shielding him from the attack. He also said that his hand had slipped. The three got angry. And the Moya Triad got upset.

Sasuke proposed another idea. The scene changed to a hot spring, as Sasuke knew that Kakashi would have to take off his mask there. Sakura, separated from the others by a fence, got envy because the hot springs had separate baths for different genders, and therefore, she would not be able to see the result of the plan. The Moya Triad, hiding behind a nearby rock, had another plan to kill Kakashi; when Kakashi came in, Aniki would shoot a poison dart at him which would send him into endless and uncontrollable laughter until he died. Kakashi then entered the hot springs, only for Sasuke and Naruto to find that he had used a towel to substitute for his mask. The two boys were surprised to find that their seemingly perfect plan had failed. Aniki then shot his poison dart, but missed when Kakashi bent over, and hit a frog instead. As Sasuke and Naruto left the bath area, Naruto noticed the Triad's clothes. A few minutes later, the Triad returned as well, only to find them missing.

The team left the motel the next morning, with the Triad following them closely (in their extra pairs of clothes). While working on the farm, the team finally thought about giving up. However, Naruto decided that it was time to move on to drastic measures. They all dressed up in the Triad's clothes (which Naruto had taken), and attempted to attack Kakashi and remove the mask by force. The Moya Triad noticed them, and found an opening to reveal themselves, only to find out that Kakashi had already defeated and tied Naruto, Sasuke, and Sakura together. When Kakashi asked them what they were doing, Sakura quickly came up with an alibi and said that the Triad had fallen for their trap, and that they had known that the Triad was tailing them. Kakashi approached the Triad, who backed away a few inches and began to beg Kakashi for mercy. He then proceeded to beat them in the same way as he had three years ago. After they had been tied up, Kakashi asked the Moya Triad who they were, showing that he had forgotten his entire encounter with them, upsetting them greatly.

As the team left for Konoha, Naruto asked Kakashi outright what was under his mask. Ironically, Kakashi agreed to show them, and prepared to take it off. Before he did so, They wondered if he had blimp lips, buckteeth, and a tiny "kissing mouth". After their intense anticipation, Kakashi finally took off his mask, only to reveal another mask underneath that was lighter in colour. While taking off his mask, he says, it's another mask, making Naruto, Sasuke, and Sakura fall to the ground in horror while Kakashi laughed. It's because their efforts were ultimately wasted. Naruto screamed, saying, "WHAT KIND OF STUPID ENDING IS THAT?!"

Trivia
