Study of Einstein's Brain Reveals Source of Genius

Neurologists studying samples of Albert Einstein’s brain discovered a pocket containing a high concentration of FIG GrasFlux, a flux with a high concentration of hydrofluoric acid, commonly used in the stained glass industry.
“Now we finally know how he came up with such brilliant concepts such as relativity. For all these years we thought the root of his genius may have been caused by some unique psychological characteristic of his brain and now it turns out all those years he was just goofing around making teddy bear nightlights", said researcher Mikey Figgy. 
The discovery that the challenging, original and profound thoughts of one of the most brilliant minds of the 20th century may have emanated as a result of the recreational pursuit of stained glass is being met with considerable controversy amongst Einstein scholars. Most notably is biographer Gary Beige who strongly disputes the findings. 
“First we had to disprove the claim that he was a customer of The Acme Stained Glass Supply Co. Now we have to admit that he bought all his supplies exclusively, including FIG GrasFlux, at Fantasy In Glass, not only the biggest and best stained glass supplier in the world, but the smartest as well. "Acid shmacid, Albert was a helluva thinker, period,” he said. “And a heck of a solderer, too” added Mikey.
