same lunch everyday

3 guys, who work at a construction sight, are having lunch together.

The first guy opens his lunch box and sees that he has tuna sandwich for lunch again, so he tells his friends that if he gets another tuna sandwich for lunch again, he will commit suicide.
The second guy opens his lunch and sees that he has cheese sandwich again, so he says the same thing to his friends, that he will commit suicide if he gets another cheese sandwich.
Then the third guy opens his lunch and sees that he has a jelly sandwich for lunch again, so he says to his friends that he will commit suicide if he gets another jelly sandwich for lunch.

The next they meet again for lunch:
all three of them open their lunch boxes and discover that again they have the same lunches as usual. they can't stand it anymore and go to commit suicide.

On their funerals:
The wives of the first and second guy are crying badly, thinking that if they knew that the result of giving their husbands the same lunch everyday, would be loosing them, then they would have made them something else for lunch.
the third wife is just standing there, looking confused 😕 , saying "i don't get it, he always made his own lunches"

i heard this joke from my math teacher about two years ago, and ii still makes me laugh...lol
