Jokes about St. Patrick's Day

Two Irishmen were walking home after a night on the beer when a severed head rolled along the ground. Mick picked it up to his face and said to Paddy "Jez, that look like Sean" to which Paddy replied "No Sean was taller than that"

It was Paddy and Seamus giving the motorcycle a ride on a brisk autumn day. After a wee bit, Paddy who was sitt'n behind Seamus on the bike began to holler ..."Seamus ... Seamus ... the wind is cutt'n me chest out!" "Well, Paddy my lad," said Seamus, "why don't you take your jacket off and turn it from front to back ... that'll block the wind for you." So Paddy took Seamus' advice and turned his jacket from front to back and got back on the bike and the two of them were off down the road again. After a bit, Seamus turned to talk to Paddy and was horrified to see that Paddy was not there. Seamus immediately turned the bike around and retraced their route. When after a short time he came to a turn and saw a bunch of farmers standing around Paddy who was sitting on the ground. "T'anks be to heaven, is he alright?" Seamus hailed to the farmers. "Well," said one of the farmers, " he was alright when we found him here .. but since we turned his head back to front .. he hasn't said a word since!"

Michael Faraday

Born 22 Sep 1791; died 25 Aug 1867 at age 75. English physicist and chemist whose many experiments contributed greatly to the understanding of electromagnetism. Although one of the greatest experimentalists, he was largely self-educated. Appointed by Sir Humphry Davy as his assistant at the Royal Institution, Faraday initially concentrated on analytical chemistry, and discovered benzene in 1825. His most important work was in electromagnetism, in which field he demonstrated electromagnetic rotation and discovered electromagnetic induction (the key to the development of the electric dynamo and motor). He also discovered diamagnetism and the laws of electrolysis. He published pioneering papers that led to the practical use of electricity, and he advocated the use of electric light in lighthouses.«
