Impossible anatomy Memes

The meme plays on the double meaning of "physics" - referring both to the academic discipline and physical fitness. The person in the chair has an impossibly muscular physique that defies normal human anatomy (hence the physics joke). The comeback is equally savage, suggesting this unrealistic body standard is likely the result of genetic inheritance rather than achievable through normal means. It's basically the scientific equivalent of "I'm studying physics by bench-pressing textbooks instead of reading them."
