An Irishman, a Mexican and a redneck were doing construction work on the scaffolding of a tall building.  They were eating lunch and 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 redneck opened his lunch and said, "Bologna again. If I get a bologna sandwich one more time, I'm jumping too."

Next day the Irishman opens his lunch box, sees corned beef and cabbage and jumps to his death.

The Mexican opens his lunch, sees a burrito and jumps too.

The redneck opens his lunch, sees the bologna and jumps to his death as well.

At the funeral, the Irishman's wife is weeping.  She says, "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 weeps and says, "I could have given him tacos or enchiladas!  I didn't realize he hated
burritos so much."

Everyone turned and stared at the redneck's wife.  "Hey, don't look at me," she said. "He makes his own lunch."
