Tabs
Explanation
The Joke
An office worker is sitting at their computer when they notice the boss approaching, shown as a dark silhouette looming behind the cubicle wall. The worker thinks: "Oh jeez, the boss is coming, better open all my porn tabs!" The caption below reads: "It was hard to adjust back to office life after my job as a porn editor."
The comic plays on the universal workplace experience of quickly switching away from non-work content when a supervisor approaches. In a normal office, a worker would frantically close inappropriate tabs. But this character has the opposite reflex -- having previously worked as a porn editor where pornography literally was the work, they instinctively try to open porn tabs to look busy, not realizing they are now in a conventional office where this would be deeply inappropriate.
The Humor
The comedy works through a clean inversion of expectations. Everyone is familiar with the panicked "alt-tab" moment of hiding personal browsing when the boss walks by. By creating a character whose previous job required viewing pornography as actual work product, Weinersmith inverts the reflex entirely. The joke also touches on the idea that our work habits become deeply ingrained -- muscle memory and instinct can persist long after changing jobs. The single-panel format with a thought bubble makes the delivery tight and punchy, letting the caption serve as the explanatory punchline.
References
The comic references the common office phenomenon of quickly switching browser tabs when a manager approaches, sometimes called "boss keying" -- a concept so widespread that some applications have historically included a dedicated "boss key" that instantly switches to a work-appropriate screen.
