Bad Einstein Pun

Albert Einstein was born March 14, 1879.

Few remember that the Nobel Prize winner married his cousin, Elsa Lowenthal, after his first marriage dissolved in 1919. He stated that he was attracted to Elsa because she was well endowed and he postulated that if you are attracted to women with large breasts, the attraction is stronger if there is also a DNA connection.

This is known as Einstein's Theory of Relative Titty.
