That Thing We Do
Explanation
The Joke
A couple is in bed, and the man suggests that after the kids are asleep, they should go to the bedroom and "do that thing we do a couple times a month" that "always goes pretty much the same way" but they somehow "never tire of." His partner responds with an enthusiastic "Ooh." The obvious implication is sex -- but in the next panel (labeled "Later"), the man is shown spending money online, and his partner asks, "Do you see me spending money on things for me? Ever?"
The punchline reveals that the recurring bedroom activity is not sex but rather the same old argument about spending habits.
The Humor
The comic works through classic misdirection. All the language in the first panel -- the bedroom setting, "after the kids are asleep," "that thing we do," the suggestive "Ooh" -- strongly implies the couple is talking about sex. The reveal that they are actually describing a recurring marital argument subverts the expectation. The humor is amplified by the fact that the setup language ("pretty much the same way," "never tire of") perfectly describes both sex and repetitive couple arguments, making the bait-and-switch feel natural rather than forced. It is a wry commentary on long-term relationships, where predictable fights can become as routine as intimacy.
