An Irishman, a Mexican, and a Blonde construction worker were eating lunch on the 20th floor of a building.  The Irishman said, "Corned beef and cabbage. If I get corned beef and cabbage one more time for lunch, I'm going to jump off this building."

The Mexican opened his lunch box and exclaimed, "Burritos again! If I get burritos one more time I'm going to jump off, too."

The blonde guy opened his lunch and said, "Bologna again! If I get a bologna sandwich one more time, I'm jumping, too."
 
The next day the Irishman opened his lunch box, saw corned beef and cabbage, and jumped to his death.
 
The Mexican opened his lunch, saw a burrito, and jumped too.
 
The blonde guy opened his lunch, saw the bologna sandwich and jumped to his death as well.

At the funeral the Irishman's wife was weeping.  She said, "If I'd known how really tired he was of corned beef and cabbage, I never would have given it to him again."

The Mexican's wife also wept and said, "I could have given him tacos or enchiladas. I didn't realize he hated burritos so much."

Everyone turned and stared at the blonde guy's wife. She looked at them and said, "Don't look at me. He made his own lunch."
