Pfizer Industries, (manufacturer of Viagra), postulated a question to the world of academia; 'What is the function of the glans as evolved in Homo Sapien?' (the knobbly bit at the end of the penis). They offered a $5M bursary to any institution that could adequately explain the mystery. Professor Torhild Skarsgård and her research team at the University of Oslo spent 4 million Krone on a 6 month long research project that concluded the glans had almost certainly evolved to enhance the female's coital experience and increase the chances of impregnation. Professor Sir Arthur Hebblethwaite and his research team at the University of Oxford spent £700,000.00 on a 9 month long research project that concluded the glans had almost certainly evolved to enhance the male's coital experience and improve the chances of paternity. Professor Paddy O'Murphy and his research team at the University of Dublin spent €27.68 (Jazz mags, KY & Kleenex) on a 12 minute long research project that concluded the glans had almost certainly evolved to stop your hand flying off the end of your cock when you're wanking.
