An elderly doctor and a Baptist minister were seated next to each
 other on the plane.
 
 The plane was delayed at the start due to some technical
 problems. Just after taking off, the pilot offered his apologies
 to the passengers and announced that a round of free drinks would
 be served.
 
 When the charming air-hostess came round with the trolley, the
 doctor ordered a gin and tonic for himself. The hostess then asked
 the minister whether he wanted anything.
 
 He replied, "Oh No!  Thank you.  I would rather commit adultery
 than  drink alcohol."
 
 The elderly doctor promptly handed his gin and tonic back to the
 air-hostess said, "Madam, I did not know there was a choice."
