Ronald Jeremy Hyatt (born March 12, 1953), usually called Ron Jeremy, is an American pornographic actor. Nicknamed "The Hedgehog," he was ranked by AVN at number one in their "The 50 Top Porn Stars of All Time" list. Jeremy has also appeared in non-pornographic films, such as The Boondock Saints and 54.
He is well known for his large 9.75-inch (~24.75cm) penis – and he has gained some notoriety for being capable of autofellatio, though he stated in a 2003 interview that due to his weight gain, all he can do nowadays is kiss the tip of his penis.
