One day the Physics professor came into his class and decided to throw a pop quiz at his students. He asked them to offer their opinions as to whether Hell was endothermic or exothermic using their knowledge of math, physics, history, general knowledge, etc. . He told them they had 45 minutes to complete the assignment. The students got busy, checking on their laptops, etc. and writing furiously. One student however just sat still and then slowly wrote down his notes, and within 5 minutes handed his paper to the professor.
“You’re finished already?” asked the professor. “Yes” replied the student. The professor read the paper, smiled and said “That’s clever thinking outside the box. I want you to read this to the entire class.”
The student began slowly “I believe I have proof that Hell is definitely endothermic because at the beginning of this semester, I met this attractive, popular girl whom I tried to hit on. She rebuffed me saying ‘It will be a cold day in Hell  before I sleep with you.’ “ Well, guess what? Things changed and last night Hell froze over.” 😈
