Olympics

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."
