There was a Mexican an Italian, and a blonde guy who were all electricians and working on the top floor of a 20 story high building. It was time for them to go to lunch. The Mexican opened his lunchbox to find a burrito and said: "If I find another burrito in my lunch tomorrow I’m going to jump off this building to my death."

The Italian guy finds cabbage in his lunch box and says the same thing as the Mexican. Then the blond guy finds a bolongna sandwich and says I’m also going to jump if I find another bolongna sandwich

It was the next day and it was time for lunch and the Mexican opens his lunch and finds a burrito and jumps off the building. The Italian finds cabbage in his lunch again and jumps off also. The blond guy finds a bolongna sandwich and jumps off too.

At the funeral the Mexican’s wife is crying and she says: "If only I knew he didn’t like burritos I wouldn’t have made them."

Then they all look at the Italian guy’s wife and she is sobbing: "If only I knew he didn’t like cabbage I wouldn’t have put it in his lunch box."

When they look at the blonde guys wife she is not crying and she says: "Well don’t look at me, he makes his own lunch."
