"Definition of Tragedy" joke

The President was visiting a grade school the other day and sat in on an English class. To participate in the class, he asked for someone to give him an example of a tragedy.

A little girl named Peggy held up her hand timidly and said,' If my friend was walking across the street and a car ran over her... well, that would be a tragedy!'

'Well, thank you for trying,' The Prez said.' That would be what we would call an accident, but not a tragedy. Can anybody else give me an example?'

A little boy named Timmy said,' If the school bus was full of kids and a truck hit it and killed all the kids that would be a tragedy.'

'Well, that would be what we call a great loss, but it doesn't quite make the tragic category,' the President replied.

About his time little Johnny held up his hand.' Oh. Oh. I know, I know...' Johnny started.' If you and the Vice President and all the senators and all the congressmen were having a meeting, and a bomb blew everybody up that would be a tragedy.'

'That's right!' the President exclaimed.' How did you figure that out?'

'Well,' said Johnny,' it wouldn't be an accident and it darn sure wouldn't be a great loss!'
