Even in the afterlife, thermodynamics gets the last laugh! Poor Joe thought he was getting off easy with Level 1 of Hell, until the devil dropped that scientific burn. "That's the hottest level, because heat rises." The ultimate cosmic irony - punished by the very science he cheated on! The devil's basically saying "Should've paid attention in physics class instead of copying answers, buddy." Science: useful for acing tests AND understanding your eternal damnation.
