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 bologna one more time I'm going to jump off too."

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