Visual joke

I was watching "The Brokenwood Mysteries," which is a show out of New Zealand. I sometimes don't understand what they're saying, so I have to turn on the subtitles 😅 It's a really good show that has really good actors; every single character, whether a small part or major one, is played by a pro. It's amazing that such a small country can produce so many skilled performers—more than a larger country that I want to mention but won't 😏

In one scene from season 4 episode 2, "Stone Cold Dead," two of the detectives are visiting the boss in a hospital, and there is poster that says, "All pain, no gain," with a picture of a woman on a treadmill. It looks like something very large is on her back. Is it a person? Luggage? I can't tell. Or maybe it's a mirage, because the image isn't clear (it's in the hallway, outside the hospital room's shaded window). But it definitely seems like a visual joke, which isn't surprising because there seems to be traces of humor among the deaths. I did a search online and couldn't find anyone discussing this, nor could I find any use of "All pain, no gain," so it's a unique creation (because, obviously, it's a flip of "No pain, no gain.")

p.s. the e-book version of my debut novel is still at Amazon, and the price for the print version has been reduced: buy at the Eckhartz Press site.
