Sanaewife finds her husband's brand of humor to be very grating.

And in a few seconds, so will Kogasa.

Reader-added tags include "C◯◯t shirishiri" (originally censoring ninjin (carrot) so it looks like it could be chinchin), "Kogasa-san on the verge of being grated", and "Sanae-san secretly bought them afterward".

This husband and wife seem to dislike each other greatly.
