Three men were in a balloon. They got caught in a storm and after
being tossed about, they got lost. When the storm calmed down, they
eventually floated passed a man on the ground. They yelled "Where
are we?" The man replied "You are in a balloon". One of the men in
the balloon turned to the others and said "that man is obviously a
lawyer". How can you tell?, the two asked. "It's easy, the
information he gave is totally accurate, and completely useless".
