How do you know what a boys restroom looks like?!

Because I saw one with your brother

No... no way, do you mean that you saw him peeing!?

Well...

Rather than peeing, phimosis. The Japanese has a pun. "urination" (放尿) is "hounyou" while "phimosis" (包茎) is "houkei"

These two really have gotten on the same wavelength. ...This is trending the right way!
