Identical-code Memes

The eternal mystery of copy-paste programming: you copied it exactly the same, yet somehow it refuses to work. Is it invisible whitespace? A missing semicolon? Or perhaps the teacher deliberately included a subtle trap to catch the copy-cats? That confused cat stare perfectly captures the existential crisis of staring at identical code that somehow produces different results. The digital equivalent of copying someone's test answers only to discover you've both failed but in completely different ways.
