TOP FIVE EXCUSES FOR NOT DOING YOUR MATH HOMEWORK
  1. I accidentally divided by zero and my paper burst into flames.
  2. Isaac Newton's birthday.
  3. I could only get arbitrarily close to my textbook. I couldn't actually reach it.
  4. I have the proof, but there isn't room to write it in this margin.
  5. I have a solar powered calculator and it was cloudy.
