Well I have never been a "client" of any ambulance service....yet. So roll out the bad jokes... George Bush is visiting a school and asks the children "What is a tragedy?" . So on child puts his had up and says "Well, what if a tree fell on the school, and, like, killed everyone?" "No sir, that would be a accident" "Well what if like a plane crashed into the Senate and killed ,like, everyone? "No sir that would be a great loss" "Ok..well... what if you and Laura were flying in Air Force One and got shot down? "And how do you know that it would be a tragedy?" "Well Mr Bush.. it wouldn't be a great loss and probably not an accident either.
