Jump out of the plane

An Englishman, Frenchman, Mexican, and Texan were flying across country on a small plane when the pilot comes on the loud speaker and says " We're having mechanical problems and the only way we can make it to the next airport is for 3 of you to open the door and jump, at least one of you can survive"

The four open the door and look out below. The Englishman takes a deep breath and hollers "God Save The Queen" and jumps.

The Frenchman gets really inspired and hollers "Viva La France" and he also jumps.

This really pumps up the Texan so he hollers "Remember the Alamo" and he grabs the Mexican and throws him out of the plane.

David Marine

Born 20 Sep 1888; died 6 Nov 1976 at age 88. American pathologist whose substantial research on the treatment of goitre with iodine led to the iodizing of table salt. During 1917-22 he ran a trial on a large group of schoolgirls to show that an iodine supplement dramatically reduced the incident of goitre (a major swelling of the thyroid gland in the neck). His results clearly showed the important of iodine in the diet. Dr. David. M. Cowie promoted the production of iodized table salt, first sold on 1 May 1924, and later throughout the U.S., greatly reducing the incidence of goitre. Marine worked on salt iodization for the World Health Organization, further spreading its benefits. (As early as 1821 French chemist Jean-Baptiste Boussingault had observed that iodine-rich salt could treat goiter.)«
