An Englishman, a Scotsman, and an Irishman were without tickets  for the opening ceremonies of the summer Olympics but hoped to  be able 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 Olympic Park, the Englishman spied  a construction site and picked up a length of scaffolding.  Returning  to the gate, he presented himself and said, "Smythe, the pole vault"  and was admitted.
 
 Seeing this, the Scotsman went to the site and grabbed a sledge  hammer and went to the gate.  "McTavish, the hammer throw."  He was  promptly admitted to the Park.
 
 After thinking a while, the Irishman combed the construction site for  an hour, and was almost ready to give up when he saw his ticket in.  Seizing a roll of barbed wire, he went to the gate and declared:  "O'Malley, fencing."
