A English man , a french man and a newfie are all constructions workers.
One day at lunch time English man opens his lunch box and finds a peanut
butter sandwich and say "if my wife makes me one more peanut butter
sandwich, I'm gonna jump off this building and kill myself. The french
man opens up his lunch box and finds a tuna sandwich and says "if my wife
makes me one more tuna sandwich, I'm gonna jump off this building and kill
myself". Then the Newfie opens up his lunch box and finds and egg salad
sandwich and says"if my wife makes me one more egg salad sanwich, I'm gonna
jump off this building and kill myself.

Sure enough, the next day at lunch, they all get the same sandwiches and
plunge to their deaths.

A few days later, at the funerals, the english mans wife says "only if
he told me he didn't like peanut butter sandwiches" The french mans wife
says"only if he told me he didn't like tuna sanwiches". Thw newfie man's
wife then says "but I don't understand, he's been making his own lunches
for weeks!"
