Sneaking into the Olympics

Three budding athletes are trying to get into the stadium for the Olympics but they forgot their passes. As they are standing there arguing with the guard a fellow comes up dressed in his jogging suit and carrying a ball in his hand. He shouts "Greece, shot put!", and the guard waves him in.

The other three see the light and one gets into his jogging suit, tears off a hubcap from a parked car, comes up to the gate and shouts "England, discus!". The guard waves him in.

The second one into suit, grabs a broom handle, gets to guard, shouts "Italy, javelin!", and gets waved in.

The third one puts on his jogging suit, wraps himself into about 30 yards of barbed wire, waddles up to the guard and shouts "Poland, FENCING!".
