An Irishman, a Mexican and an Alabama redneck were doing construction work on scaffolding on the 20th floor of a 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 Alabama 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 open his lunch, sees a burrito and jumps too. The Alabama redneck opens his lunch, sees the bologna and jumps to his death also.
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 Alabama redneck's wife. "Hey, don't look at me," she said, "He makes his own lunch!"
