Sean, Juan and Billy Jack were doing construction work on scaffolding on the 20th floor of a building. They were eating lunch and Sean 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."
Juan opened his lunch box and exclaimed, "Burritos again! If I get burritos one more time I'm going to jump off, too."
Billy Jack opened his lunch and said, "Bologna again. If I get a bologna sandwich one more time I'm jumping too."
Next day the Sean opens his lunch box, sees corned beef and cabbage and jumps to his death. Juan opens his lunch, sees a burrito and jumps too. Billy Jack opens his lunch, sees the bologna and jumps to his death also.
At the funeral - Sean'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!" Juan'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 Billy Jack's wife. "Hey, don't look at me" she said. "He made his own lunch."
