Three construction workers have had it with their sandwiches being the same for the last 20 years! So they struck a deal, if their wives make them same sandwiches yet again, tomorrow, they’re gonna throw themselves off the building.
So tomorrow comes, and one opens his lunchbox, sees the same sandwich, and jumps to his death. The second one opens his lunchbox, same story, jumps. And the third one opens his, sees another same sandwich as yesterday, and jumps off to his demise.
At their funeral, the first construction worker’s wife cries, and through her tears says “He should have told me, I would have made him a different sandwich”. The second wife totally devastated whimpers “He never complained about his sandwich, I should have known…”, and continues crying. And the third one cries “Oh what an idiot I married, he made his own sandwiches”
