Microwave

comic

Bingo: Hey Argent, what’s wrong with Cyn?

Argent: You know of shared office microwaves?

Bingo: Yeah…

Argent: The sort that are always somewhat dirty, though every once in a while someone wipes off the plate and walls?

Bingo: Uh-huh…

Argent: She went to clean off the plate and noticed the microwave ceiling for the first time. “Interesting geography” was the phrase, I believe.
