Right

Richard and Al were on a small chartered airplane when the pilot suddenly had a heart attack.  "Don't Panic," cried Richard heroically. "I'll land this baby!"  Seizing the controls he headed for the runway at LaGuardia Airport, and began wrestling the diving plane to the ground.  Just as the wheels touched the ground, Al screamed, "Red lights!! Right in front of you!" Immediately Richard threw the engine in reverse and jammed on the breaks, bringing the plane to a violent stop just inches from the edge of the lights.  "Brother!" he puffed, wiping his brow.  "That sure was a short runway!"  "Yeah," agreed Al, looking side to side, "but look how WIDE it is."

The 50-50-90 rule: Anytime you have a 50-50 chance of getting something right, there's a 90% probability you'll get it wrong.
