The image depicts a somewhat absurd and humorous sight: a whole, uncut slice of pizza immersed in a pot of boiling water as if it were intended to be cooked in this manner. The pizza slice, with visible pepperoni toppings, is submerged in the water, which indicates the involvement of a cooking process that is completely unconventional for pizza.
Above the photo is a caption that reads, "This is what happens when white belts are teaching each other." The term "white belts" is a reference to martial arts, where practitioners wear belts of different colors to signify their level of expertise, with white belts indicating novices or beginners.
The humor in the image arises from the incongruity of cooking methods and the analogy drawn between inexperienced martial artists and someone attempting to cook in an unorthodox manner. The boiling of a pizza, something that is typically baked, grilled, or reheated in an oven, is laughable because it demonstrates a lack of basic culinary knowledge or skill.
The caption adds to the humor by implying that the mishap is the result of novices or inexperienced individuals trying to instruct one another without proper guidance. This plays on the idea that learning from someone who is also just a beginner can lead to misunderstandings or improper techniques being passed on, much like the misguided attempt to cook pizza in boiling water.
The image might be funny to people because it resonates with the common experience of cooking gone wrong, especially when attempting something new or when following questionable advice. It humorously captures a "learning by trial-and-error" situation taken to an extreme.
The absurdity of boiling a pizza, paired with the joke about inexperience and self-instruction, strikes a chord as it's not what anyone would expect in a normal cooking scenario. It's an example of visual humor where the gag is self-evident, needing no further explanation beyond the juxtaposition of the ill-suited cooking method and the item being 'cooked.' This is what happens when white belts are teaching each other
