Sandwich Costume

Human "Sandwich"

A parade line of humans dressed as bread, cheese, meat, and tomato forms a structurally convincing sandwich that still fails the crucial requirement of being lunch. It is the kind of edge case that makes literalists sound insane and compositionalists sound worse.

Under development: this benchmark and its published results are provisional, not final.

Selected human comments

  • No, it is a photo of a human sandwich.
  • only if they were all smooshed together! but separated? nope, that's ingredients
  • Is that Ranger Igor wearing the tomato? This is clearly a flock of Rangers, not a sandwich!

allenai/molmo-2-8b comments

  • While the sandwich-making characters are humorous, a real sandwich requires bread as an essential component. These costumes represent ingredients rather than the complete sandwich.
  • This image depicts people dressed as sandwich ingredients, but they are not actual food items. However, as they represent the components of a sandwich, the overall concept is still a sandwich.

anthropic/claude-sonnet-4.6 comments

  • Five people costumed as sandwich components (bread, cheese, meat, pickle, tomato, bread) marching in parade formation. Collectively, they ARE a sandwich. Arguably the most structurally accurate sandwich ever documented.
  • Five people dressed as sandwich components (bread, cheese, meat, onion, tomato, bread) in a parade. Collectively, they form a sandwich. Technically assembled, this BLT-ish creation qualifies, even if the ingredients are human.
