An Englishman, a Scotsman and...
An Englishman, a Scotsman and an Irishman were trying to get in to see the Olympics without tickets. So they got to the stadium during one of the main events and discussed how they would be able to attend without paying.
The Englishman walked around the stadium and saw a pole lying on the ground and picked it up. He walked to the entrance and said, "Peter. England. Pole throwing." The guards let him in without hesitation.
While walking, the Scotsman sees a manhole. He picks up the cover, carries it under his arm to the entrance and says, "McGregor. Scotland. Discus throwing." The guards let him in also.
The Irishman is very frantic, since both his friends are now inside. He walks around the stadium and finds a roll of barbed wire. He picks it up, walks to the entrance and says, "Murphy. Ireland. Fencing."

First Liberty ship launchedIn 1941, the first Liberty ship, the S.S. Patrick Henry, was launched. Three months later, on 30 Dec 1941, it was delivered at Baltimore, Maryland, to the U.S. Maritime Commission. It was built in 244 days by the Bethlehem-Fairfield Shipbuilding Co., of that city. It was the first of 2,741 Liberty ships launched, of which 385 were built at Baltimore, in a three-year WW II emergency merchant ship construction program. The S.S. Patrick Henry could average a speed of about 11 knots, and had a general cargo capacity of 9,146 tons. The American patriot Patrick Henry had ended a speech (23 Mar 1775) with the phrase “give me Liberty, or give me death,” Hence the emergency ships became known as Liberty ships, after President Roosevelt said their mission was to bring liberty to European allies with relief supplies.« |
