A Difference in Definitions

A lawyer and an engineer are arguing at a bar about who has the more honest profession. The lawyer says, 'As an attorney, I simply practice the truth until it works.' The engineer shakes his head and says, 'That’s the problem. In my job, if I practice the truth and it doesn't work, the bridge falls down.'

The lawyer shrugged and replied, 'Well, that’s why I specialize in bridge law, I prefer to work with things that have already collapsed!'
