A Jew, a German, and and an Irishman are stranded in the desert. The German falls to his hands and knees and cries out, ""I'm tired! I'm thirsty! I need a nice German beer."" The Irishman does the same, mumbling, ""I'm tired! ""I'm thirsty! I need a Guinness."" The Jew looks down and says, ""I'm tired! I'm thirsty! I must have diabetes.""
