On the Blackboard

A lawyer happened to pass next and when he saw what the priest had written, he added under it, 'I'm a lawyer and I defend you all.'
Then a doctor came by, took the piece of chalk and wrote on the blackboard, 'I'm a doctor and I cure you all.'
Finally an ordinary citizen stopped, looked at what the others had written, thought for a few seconds and then added, 'I am a ordinary citizen and I pay for you all.'
