yet
Explanation
The comic shows a person sitting in a large leather swivel chair behind a desk, facing their spouse (Dr. Williams). The seated person dramatically intones: "Well well well, Dr. Williams. Seems you've caught me red-handed. But is all... as it seem--" and the spouse cuts them off with: "Yes. It's your turn to mow the lawn. Stop it!"
The caption reads: "Ever since I got an oak desk and a rotating leather chair, I don't mind routine fights with my wife."
The humor is about how owning a dramatic villain chair transforms mundane domestic disputes into theatrical confrontations. The person has adopted the persona of a Bond villain or evil mastermind, slowly swiveling in their leather chair to face their accuser, speaking in ominous dramatic cadences -- all over something as trivial as whose turn it is to mow the lawn. The spouse, clearly used to this behavior, is having none of it.
The title "yet" likely refers to the unfinished "as it seem--" being cut off before the character can add "yet" or complete their dramatic monologue. The comic plays on the universal fantasy of having a dramatic villain lair and the gap between wanting to be a mysterious mastermind and the reality of domestic chores.
