These two guys, George and Harry, set 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, lets ask that guy on the ground". So Harry
yells down to the man "Hey, could you tell us where we are?". And
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 is 100% accurate, and totally
useless".
That's the end of the Joke, but for you people who are still
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".
