Joke: "Dye My Hair"

A 70-year-old woman went to a barber's shop to get her hair cut and asked the barber, "How much is the dye?"

The barber replied, "80 yuan."

Old lady: "It's too expensive, isn't it 40 yuan for half?"

Barber: "Well, if you want."

Old lady: "Well, you only dye the white ones black, and leave the black ones alone!"
