Blind pilots
One day at a busy airport, the passengers on a commercial airliner are seated, waiting for the cockpit crew to show up so they can get under way.

The pilot and copilot finally appear in the rear of the plane, and begin walking up to the cockpit through the center aisle.

Both appear to be blind. The pilot is using a white cane, bumping into passengers right and left as he stumbles down the aisle, and the copilot is using a guide dog. Both have their eyes covered with huge sunglasses.

At first the passengers do not react; thinking that it must be some sort of practical joke. However, after a few minutes the engines start revving and the airplane starts moving down the runway.

The passengers look at each other with some uneasiness, whispering among themselves and looking desperately to the stewardesses for reassurance.

Then the airplane starts accelerating rapidly and people begin panicking. Some passengers are praying, and as the plane gets closer and closer to the end of the runway, the voices are becoming more and more hysterical.

Finally, when the airplane has less than 20 feet of runway left, there is a sudden change in the pitch of the shouts as everyone screams at once, and at the very last moment the airplane lifts off and is airborne.

Up in the cockpit, the copilot breathes a sigh of relief and turns to the pilot: "You know, one of these days the passengers aren't going to scream, and we're gonna get killed!

Advice from lawyers
George and Lenny decide to cross North America in a hot air balloon. However, neither were particularly experienced balloonists, and Lenny's mind quickly drifted from navigation to thoughts of how clouds look like cuddly little bunny rabbits. Upon realizing that they were lost, George declared, "Lenny -- we are going to have to lose some altitude so we can figure out where we are."

George lets some hot air out of the balloon, which slowly descended below the clouds, but he still couldn't tell where they were. Far below, they could see a man on the ground. George lowered the balloon, to ask the man their location.

When they were low enough, George called down to the man, "Hey, can you tell us where we are?" The man on the ground yelled back, "You're in a balloon, about 100 feet up in the air."

George Called down to the man, "You must be a lawyer." "Gee, George," Lenny replied, "How can you tell?" George answered, "Because the advice he gave us is 100% accurate, and is completely useless".

The man called back up to the balloon, "You must be a client." George yelled back, "Why do you say that?" "Well," the man replied, "you don't know where you are, or where you are going. You got into your predicament through a lack of planning, and could have avoided it by asking for help before you acted. You expect me to provide an instant remedy. The fact is you are in the exact same position you were in before we met, but now it is somehow my fault."
