the humor in this oneshot was not up to snuff compared to the Lee and Sasuke SD either.
Part of it has to do with the recycled jokes.
A character does something ridiculous and others, including the serious character, praises it while the only 'sane characters' wonders what is wrong with everyone. It's been done before SO MANY times in many comedy series (including Lee and Sasuke SD). Now on its own that is NOT a problem because it can be legitimately funny. The problem is Sexy Jutsu isn't funny (even Naruto never found it funny and only used it to mess with and/or bribe his perverted teachers. I'm pretty sure that at 13 (after maturing a little) he was disgusted by anyone who fell for it). Sexy Jutsu on its own isn't outlandish enough to be ridiculous and so much of the humor was lost for me.
And using a surprising mundane and kinda stupid move in an important battle also can be really funny. But lemon juice was random in a 'LOL RANDOMZ' kinda way as opposed to a 'haha that's random' kind of way. Unless there's a joke I'm not getting, it was WAY too out there for the setting/characters to be funny. It was just, to be frank, stupid.
The other part is the characters.
We don't really know anything about ANY of them except Sarada and even she acted different. I understand making her the straight man but she wasn't shown to be violent in gaidan and so yes, that was a terribly cheap tactic to parallel her to Sakura (I would understand if she got angry because Bolt put her mother in there. We could've got a hilarious chase scene from that. But a standard 'stop fooling around'? I would've never guessed Sarada would get THAT upset over that). Bolt is a brat but instead of drawing humor from that he was basically a stand in for Lee (only less sympathetic. Lee was fun because of his genuine enthusiasm and naive nature meant that he would do everything with a gusto and seriously believe that what he was doing was cool. Bolt is a brat but supposedly born into greatness.) And who the hell cares about Mitsuki's and especially Konohamaru's opinion (Konohamaru hasn't been relevant since his introduction).
I mean I don't know if it was just me or what but this was not at all funny to me.
