Road and Aisle

Zさん："If you're like me, you struggle with the Japanese words 通路 and 道路 because they look almost identical. 通路(tsuuro=aisle) 道路(douro=road). Quick tip: the first kanji of tsuuro has a pointy つ at the top, and douro is road spelled backwards."
Aさん：「... and いならまつ is つまらない spelled backwards.」

Lit Pun

Zさん："What is your online group for?"
Aさん：「We're taking a survey of whether people know of and have read "The Canterbury Tales".」
Zさん："... so... it's... Chaucerの調査？"

There and Back Again

Zさん："The Japanese word 戻る (modoru) means to return/go back. Kinda sounds like where Frodo Baggins had to... well... return the ring of power."

Food Nerd

Zさん：“… it was literally the best deconstructed gyoza I’ve ever eaten.”

Aさん：「Wow, you are quite the foodie!」

Zさん：”Yeah, I like to think of myself as a Gohan Otaku.”

Cさん：「ご飯を炊く？あの、あまりグルメではないかな。。。」
