* Any time Arino beats a notoriously difficult game, such as ''{{VideoGame/Battletoads}}'', ''VideoGame/NinjaGaiden'', and ''[[VideoGame/GhostsNGoblins Super Ghouls 'n Ghosts]]''.
* In the ''VideoGame/GhostsNGoblins'' playthroughs, when Arino first meets the Red Arremer he [[KnowWhenToFoldEm runs away]], losing a life but skipping the demon by reaching a checkpoint. It's very satisfying to see him getting over his fear and carefully taking down the Arremers when forced to fight them in the end-game.
* Despite having some trouble with stages 2 and 4, Arinoppa the Rapper beat ''ParappaTheRapper'' in just about 4 hours.
* Any time Arino finishes a game on a 24-hour or less live events.
-->''"DO [[VideoGame/TheQuestOfKi KI]]."''
-->--A fax from Kawaguchi, when Arino was getting sidetracked by ''Spelunker''

-->''"I did Ki. I DID IT!!"''
-->--Arino's response after beating the game [[DownToTheLastPlay with 4 minutes left]].
** His victory on his third attempt at ''Pilotwings'' was truly miraculous. On his last try and with little time left, he had finally finished off all the enemy turrets on the last level. Under immense pressure, he still had to land the helicopter successfully, which he does, ''right as the game started complaining he was descending too fast!''
* Arino finishing ''Ninja Spirit'' in a mere 2 hours, largely thanks to pure luck getting him through an extremely difficult FreeFallFight which took the ADs 5 hours to do the same.
* The AD's have their own Crowning Moments of Awesome, including...
** The "Ace" Urakawa finally beating VideoGame/AdventureIsland after [[{{Main/Determinator}} 28 straight hours]].
** Inoko MAX, having spent most of the fifth season screwing up in one way or another, redeems himself in the finale by getting the good ending of "Shadow Land". Much later, in Season 16, he gets another when Arino bets on him in Barcode Battle and he wins.
** Though not an AD, sound guy Fukuawa volunteered to attempt the good ending of ''Densha de Go!!'' by playing the Yamanote Line without continuing. None of the staff thought he could do it, especially since it was his first time ever playing the game. He completed it in ''six hours''.
* From ''VisualNovel/TokimekiMemorial'', Arino successfully romances Shiori on his first try, a feat considered near impossible.
* One celebration of the [[MilestoneCelebration ten year anniversary]] isn't enough. They're celebrating the whole year.
