pencil head

Couldnt sleep. So i was reading this book that i borrowed from one of the prestigious libraries and found that some one had been underlining quiet a lot. Probably one of those students i thought. I started following the pencil lines and as i was making my mind up on where this guys research was leading to, i found the below mentioned line written bold in the middle of the book.

Hey pencil-head, observing your behaviour throughout this book i diagnose you a selfish, inconsiderate scoundred. grow up..

It cracked me up.
