Once there was a person. This person saw that there was a problem: colored inks were being made from endangered plants and animals.
"I have an idea", said the person. "Everything should be printed in black-and-white."
She contacted her local newspaper (one of the worst users of colored inks) and suggested it. The newspaper person said she'd sleep on it.
As she tried to sleep, the newspaper person thought about the idea and how angry she was that someone would want that. She knew that her paper would not sell as much if it were in black-and-white, so she decided she'd keep the red and get rid of the other colors.
As she woke the next day, she was in a wondering mood. The dead chicken in the road made her wonder especially. Then she passed a herd of buffalo from New York and noticed that those buffalo who were bullied in the group tend to bully the others.
When she got to work and people asked her how she was she replied, "Well... colorless green ideas sleep furiously, but I've decided to make our newspaper be black and white and red all over. In other news, I've noticed that Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo. Oh, and does anyone know– Why did the chicken cross the road?"
