Ran over cell phone with mower and the cell phone was barely scratched.

My friend Mark was mowing his yard with his big riding mower yesterday, his cell phone fell out of his pocket, he did not notice, and he ran over it with his mower. Miraculously, the phone is not injured. All that happened was the blade caught the corner of the cover and destroyed it. That is almost unbelievable.
Mark is a lucky guy! My phone got run over by a fire truck last month. It was not so lucky.
