Deron Williams goes in to the barber and says, "give me a stoplight."
The barber says, "stoplight? What are you talking about?"
So Deron Williams says, "you know, red, yellow, green."
And the barber says, "I know what a stoplight is, but it's not a haircut."
Then Deron Williams says, "sure it is. Let my beard go, stop my hair from growing on my temples, and be careful with the top — I don't have much to work with up there."
