The Doraemon manga began in the 1970's under the duo collectively known as Fujiko F. Fujio. The name was noted for being associated with a unique art style one can instantly spot by looking at it, and aside from Doraemon, it has been used in Perman, Chinpui, and ESPer Mami.
The basic premise is that the manga centers around a bit of a loser kid, Nobita Nobi. He's on such a track to failure that a robotic cat named Doraemon has been sent to make sure things go better. Nobita, on the other hand, purely has his own desires in mind for Doraemon's tech, and uses them to try and be as cool as the showoff Sueno, outsmart the bully Gian, and win the heart of our focus character, Shizuka Minamoto.
It backfires. All the time.
One notable aspect about the manga is that Shizuka loves to take baths. She takes them constantly, on a regular basis. And she never gets to finish them, because she's always interrupted by Nobita using his gadget of the week. Her catchphrase when this happens "Nobita, you pervert!" has become something of a meme in the Japanese fandom, as has the moments themselves.
The manga's been going on for a long time, so I wanted to present some of the more notable scenes.
Exhibit A: In this chapter, Nobita has a device on him that he can use to get other people to do what he wants, sounding suave while doing so, too. When he stumbles upon the bathing Shizuka, he tries to convince her that nudity is natural, citing Adam and Eve. Shizuka agrees... and becomes a militant nudist, stepping outside her house totally naked.
