"An Irishman, a Mexican and an..." joke

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 opens 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 two
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!"
