George and Harry out in a hot air balloon to cross the Atlantic Ocean.
After 37 hours in the air, George says, " Harry, we better lose some altitude so we can see where we are".
Harry lets out some of the hot air in the balloon, and the balloon descends to below the cloud cover.
George says, " I still can't tell where we are, let's ask that guy on the ground."
So Harry yells down at the man, " Hey, could you tell us where we are?"
The man on the ground yells back, " You're in a balloon, 100 feet up in the air".
George turns to Harry and says, " That man must be a lawyer".
And Harry says, " How can you tell?"
George says, " Because the advice he gave us was 100% accurate and totally useless".
That's the end of the joke, but for you people who are worried about George and Harry:
They end up in the drink, and make the front page of the New York Times: " Balloonists soaked by lawyer".
