Three railroad construction workers, a Chinese man, an Italian, and a redneck, are all sitting down to lunch. Man, the Chinese man says. If I get another egg roll in my lunch, I'll kill myself. Man, the Italian says. If I get another slice of pizza in my lunch, I'll kill myself. Man, the redneck says. If I get another ham 'n' cheese sandwich in my lunch, I'll kill myself. The next day, all three men get the same lunches, and they all three throw themselves in front of an oncoming train. At the funeral, everybody's crying. This is all my fault! says the Chinese man's wife. If only I hadn't packed an egg roll that day. This is all my fault! says the Italian's wife. If only I hadn't packed a slice of pizza that day. Don't look at me, says the redneck's wife. He packed his own lunch.
