Lunch Anyone??

There was a japanese,hawaiian,and portugese men. They were all
working on a building when the lunch bell rung. All three men
sit down and open their lunch boxes.
The japanese man opens his lunch box and says Ah..man if I get
spam musubi again I am going to jump of this building.
The hawaiian man opens his lunch box and says ah..man if I get
lau lau again I am going to jump of this building.
The portugese man opens his lunchbox and says Ah.. man if I get
a tuna sandwich again I'll jump of the building.
The next day while the three men were working on the building
the lunch bell rang. They all sit down and open their lunch
boxes.
The japanese man says yes I did not get the same thing for lunch
I won't jump of the building.
The hawaiian man says all right I didn't get the same thing for
lunch,now I don't have to jump of the building.
The portugese man holds up a tuna sandwitch from his lunch box,
then he jumps of the building.
The hawaiian man was laughing then the japanese man asks why he
was laughing.
The japanese man says I don't get it, he makes his own lunch.
