Drunken Lid

Gian visits Suneo to angrily complain about their current stamp collecting hobby, namely, despite having started collecting stamps together around the same time, Suneo's larger amount of pocket money resulted in him outpacing Gian rather quickly. Sensing Gian's anger wrapping around his neck (literally), Suneo is left with no other choice but to give part of his collection to Gian. Suneo later meets up with Nobita to complain about this event, but he becomes even more frustrated when Nobita laughs on his misery and kicks him in anger.

Nobita comes home to Nobisuke and his friend getting drunk on beer in the living room and having the time of their lives. Feeling that it's not fair that only adults can drink their misery away, Nobita complains to Doraemon about the situation. Intrigued, Doraemon brings out the "Drunken Lid" which is capable of allowing the user to experience drunkenness through any non-alcoholic drink. Doraemon then tells Nobita to bring a bottle of orange juice from the kitchen, which he then serves to Nobita after pouring the juice through the lid. The juice soon gets Nobita drunk, though only for a few seconds as he had only taken one measly sip from it. Doraemon and Nobita then decide to go to Shizuka's house and show her the gadget. Along the way, the two run into Gian and Nobita almost gives away the information about the gadget to him but is stopped in time by Doraemon who strictly informs Nobita that telling Gian about the gadget is a "good way to never be able to get it back".

At Shizuka's house, Doraemon, Nobita, and Shizuka proceed to throw a small "drunken Cola" party, which result in the three dancing mindlessly. After the party has ended but not the drunkenness, Doraemon and Nobita run into Gian again and absentmindedly giving the gadget to Gian to help him "cure his depression". The two regain consciousness soon after and blame the drunkenness for causing them to give away the expensive gadget to Gian. Around the same time, Gian runs into Suneo, who is on his way to his cram school, and forces him to come to his house for a small Cola party, which Suneo begrudgingly accepts. Later, after the two become drunk and Gian throws in a concert, Suneo begins to act more out of his character, becoming aggressive and temperamental and calling Gian out for his non-existent singing talent. Realizing that Suneo might be drinking too much for his own good, Gian calmly reminds Suneo that he still has to go to cram school. Suneo however ignores this and instead orders Gian to go buy more Cola after their reserve has run out.

Getting almost twice as drunk as before, Suneo proceeds to recite all of Gian's bad deeds as the latter feels more and more miserable from Suneo's harsh words. After Gian sinks down and tearfully apologizes, Suneo orders Gian to return not only the stamps that Gian has taken from him, but also all the toys, books, and items to all the other kids. The episode ends with Doraemon and Nobita receiving their stuff back, including the Drunken Lid, with them worrying about Suneo's fate once the drunkenness is lifted from both him and Gian.
