An airline pilot wrote that on this particular flight he had hammered
his ship into the runway really hard. The airline had a policy which
required the first officer to stand at the door while the passengers
exited, give a smile, and a "Thanks for flying XYZ airline."  He said
that in light of his bad landing, he had a hard time looking the
passengers in the eye, thinking that someone would have a smart 
comment.
Finally everyone had gotten off except for this little old lady walking
with a cane. She said, "Sonny, mind if I ask you a question?" "Why no
Ma'am," said the pilot, "What is it?" The little old lady said, "Did we
land or were we shot down?"
