An irate father stormed into the principal's office.
- I demand to know - he screamed.
- why my son Winslow was given a zero on his English examination.
- Now, don't get excited - said the principal.
- We'll get your Winslow's English teacher in here. I'm sure she has some explanation.
A few minutes later, the English teacher arrived.
- Why did you give Winslow a zero on his English final? - demanded the father.
- I had no choice - said the schoolmarm.
- He handed in a blank paper with absolutely nothing on it.
- That's no excuse - shouted the father.
- You could have at least given him an 'A' for neatness!
