Oh, Ok

Zさん："Sometimes romaji can be much more pragmatic than ひらがな and カタカナ。For romaji, if one pronounces the letter 'O', then one's mouth forms the shape of the letter 'O'. I have never seen anyone form their mouth in the shape of 'お', or even 'オ'."

Small Namesake

Aさん：「Hi, Zさん。I'd like you to meet my new girlfriend, Allison.」
Allison："Nice to meet you."
Zさん："Nice to meet you too.  So... do you have a cousin, クモちゃん？"
Aさん：「。。。」

Pachelbel's Canon

Zさん："Ever notice how deeply engrained "Pachelbel's Canon" is in the Japanese musical psyche?  It is heard in loudspeakers of almost all department stores and train stations.  Innumerable J-POP songs pilfered the chord progression, and layered it with lovelorn lyrics.   The funny thing is, most Japanese people realize this and don't seem to mind!  I guess if you find something that works, don't reinvent the wheel of fifths."

Petting Zoo

Zさん：“This place is bizarre! None of the animals have genders! Gender-less ponies, gender-less pigs, gender-less goats, even this chicken! 変かな！”
Aさん：「ルースターかな。。。」
Zさん：“... Exactly!”
