old sailor: "An Englishman, a Scotsman and an Irishman each order a Guiness in a pub. Upon being served, each finds a fly in their beer. Repulsed, the Englishman sends his back. The Scotsman gently flicks the fly out of his mug and begins drinking. The Irishman, carefully lifts the fly up by its wings and screams, "Spit it out! Spit it out!"
