man overseas fighting a war
While a man was overseas fighting a war he received a "Dear John" letter from his girlfriend.
In the letter she explained that she had slept with two guys while he had been gone and she wanted to break up with him.
To add injury to the insult, she said she wanted back the picture of herself that she had given him.
So the Marine did what any squared-away Marine would do. He went around to his buddies and collected all the unwanted photos of women he could find.
In all, he got more than 25 pictures of various women (some with clothes and some without).
He then mailed them to his now-former girlfriend with the following note:
"I don't remember which one you are. Please remove your picture and send the rest back."

Harold C. UreyDied 5 Jan 1981 at age 87 (born 29 Apr 1893). American scientist awarded the Nobel Prize for Chemistry in 1934 for his discovery of deuterium, the heavy form of hydrogen (1932). He was active in the development of the atomic bomb. He contributed to the growing basis for the theory of what was widely accepted as the origin of the Earth and other planets. In 1953, Stanley L. Miller and Urey simulated the effect of lightning in the prebiotic atmosphere of Earth with an electrical discharge in a mixture of hydrogen, methane, ammonia, and water. This produced a rich mixture of aldehydes and carboxylic and amino acids (as found in proteins, adenine and other nucleic acid bases). Urey calculated the temperature of ancient oceans from the amount of certain isotopes in fossil shells. |
