The olympics
 

An English man, a Scots man and an Irish man 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 English man 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 Scots man 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 Irish man 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."
