Cork Screw
Gary and Martin were standing at the urinals in a public lavatory, when Gary glanced over and noticed that Martin's penis was twisted like a corkscrew. "Wow," Gary said. "I've never seen one like that before."
"Like what?" Martin said.
"All twisted like a pig's tail," Gary said.
"Well, what's yours like?" Martin said.
"Straight, like normal," Gary said.
"I thought mine was normal until I saw yours," Martin said.
Gary finished what he was doing and started to give his old boy a shakedown prior to putting it back in his pants. "What did you do that for?" Martin said.
"Shaking off the excess drops," Gary said. "Like normal."
"&%$#@ !," Martin said. "And all these years I've been wringing it."

Martin GardnerBorn 21 Oct 1914; died 22 May 2010 at age 95. American science writer who, for 25 years,wrote the highly popular “Mathematical Games” column for Scientific American. Though not an academic, nor having ever formally studied maths or science, he wrote widely and prolifically on both subjects, in such popular books as The Ambidextrous Universe and The Relativity Explosion. Since childhood, he was fascinated by magic, so one of his first books was Mathematics, Magic and Mystery (1956), about the maths of popular magic tricks. His interests grew wider and deeper. By age 42, he wrote his first column for Scientific American, and for many years thereafter popularized mathematics by highlighting puzzles that were elegantly understandable. He both inspired professionals and enchanted young readers to take an interest in mathematics.« |
