You remember in sex-ed class how you had to take a cup around and swap some water. And at the end the teacher would add some chemical and the contaminated cups' water would change color. But since its grade school it ends up being just one dude and like 4 or 5 girls with contaminated water instead of the majority of the class.
Yeah, this just kinda, maybe a little ,teeny teensy , weeny bit reminded me of the annoying feeling of no girls swapping water with me.
On the other had it's funny with an idiot non eunuch MC.
