Irish joke for the day

Rico says it an old one, but appropriate for this year's Olympics in London:

An Englishman, a Scotsman, and an Irishman were without tickets for the opening ceremonies of the summer Olympics, but decided to try to talk their way in at the gate. Security was very tight, however, and each of their attempts was met with a stern refusal. While wandering around outside the stadium, the Englishman came upon a construction site, which gave him an idea. Grabbing a length of pipe, he presented himself at the gate, saying: "Johnson, pole vault" and was admitted. The Scotsman, overhearing this, went at once to search the site. When he came up with a sledge hammer, he presented himself at the gate, saying: "McTavish, hammer throw." He was also admitted. The Irishman combed the site for an hour, and was nearly ready to give up, when he spotted his ticket into the Games. Seizing a roll of barbed wire, he presented himself at the gate and announced: "O'Hegarty, fencing."

Rico says the Irishman is named in honor of Rico's old and dead (alas) friend, Charles O. Hegarty...
