The taxonomy department is having a meltdown right now! Someone clearly skipped the chapter on what makes birds and mammals different. Last time I checked, birds have feathers and lay eggs, while mammals have hair and nurse their young.
This meme hilariously flips biological classification on its head by labeling a skinny human as the "strongest bird" and a muscular human as the "weakest mammal" — creating a paradox that would make Darwin facepalm so hard he'd evolve a handprint on his forehead.
The real comedy is that humans are mammals regardless of their physique, making this the biological equivalent of calling a square the "roundest triangle." My taxonomy professor would need therapy after seeing this.
