The internet is full of clever jokes and memes, but some require a sharp eye and a high level of observation to truly appreciate. One such joke has been circulating, featuring a seemingly simple mathematical symbol: “-4°”. However, upon closer inspection, this isn’t just about temperature—it’s a hidden visual pun.
This joke is a perfect example of how perception plays a key role in humor. At first glance, it seems like a regular conversation about slow texting and being in cold weather. But if you look closer, there’s something much funnier going on. Let’s break it down step by step.
The Conversation That Sets Up the Joke

The meme begins with a familiar text conversation:
Her: Why are you replying so slowly? Do you have someone else?
Me: Sorry, I’m at “minus 4 degrees.”
At this point, most people would assume the response is about being in a very cold place, which might explain the slow texting. However, the real punchline is hidden in the way the “-4°” symbol is visually arranged.
Breaking Down the Hidden Meaning
What makes this joke so brilliant is that the “-4°” symbol is designed to look like a stick figure sitting on a toilet.
- The “-” (minus sign) represents the base of the toilet seat.
- The “4” is shaped like a person sitting down with bent legs.
- The “°” (degree symbol) resembles the person’s head.
Once you notice this, the meaning of the conversation completely changes. The person isn’t talking about cold weather—they are actually on the toilet! That’s why they are replying so slowly!
This level of humor plays on visual trickery and forces the viewer to engage with the image in a more analytical way. It’s not just a joke—it’s a puzzle disguised as humor.

Why This Joke is So Clever
- It’s a Play on Perception
Most people take text at face value. If someone says “-4°”, we automatically assume they are talking about temperature. However, the meme subverts this expectation and turns it into a visual gag.
- It Requires Careful Observation
At first, the joke makes no sense—until you look closer. The humor comes from the realization that what seemed to be a regular text response is actually a hidden drawing.
- It Creates an “Aha!” Moment
Good jokes often involve an element of surprise. This meme tricks the brain into seeing something ordinary before revealing something completely different, making it feel more rewarding when you “get it.”
- It’s a Great Example of Optical Illusions in Comedy
Much like famous optical illusions that contain hidden images, this joke relies on how the brain processes symbols. It’s a minimalist design with a maximum effect.
Other Jokes That Use the Same Concept

This isn’t the first time the internet has played with hidden images and unexpected meanings. Here are some similar jokes and visual tricks that follow the same concept:
- The “69” Chair Illusion
Some people see the number 69, while others see a person sitting in a chair.
- The “Duck or Rabbit” Illusion
A famous drawing where you can see either a duck or a rabbit depending on how you look at it.
- “This is Not a Pipe” Art
A painting of a pipe with the words “This is not a pipe,” forcing the viewer to question reality.
Just like these examples, the “-4°” meme challenges the brain and makes us laugh at our own assumptions.
The Science Behind Why This Joke Works
Psychologists call this “pattern recognition”—the brain’s ability to find familiar objects in random patterns. This is why people see faces in clouds or animals in rock formations.

In this joke, the brain initially fails to recognize the “-4°” as a figure on a toilet. But once it makes the connection, it cannot be unseen. This sudden realization releases dopamine, making us feel amused.
Final Thoughts: Only With Infinite IQ Can You Understand!
This meme is a perfect example of how humor and perception work together. At first, it seems simple. But with a little effort, it reveals an entirely different meaning. It’s funny, clever, and interactive—everything a great joke should be!
So next time someone asks why you’re replying so slowly, just tell them you’re at minus 4 degrees—and see if they are smart enough to figure it out!
