"one heck of a display of athleticism."

Hopefully from both humans and crocodiles.

Given the choice, none of the events would be anywhere near me, but my commute takes me along the Inner City Bypass, which is directly under where they're allegedly going to build the Victoria Park stadium. Ugh, roadworks. I'll be taking my bike along the riverside bike paths instead, if my aging body can still handle it by then.

Or just hold them in Athens where it originated, or better yet, abolish them altogether.

From The Doubter's Companion: The Dictionary of Aggressive Common Sense:

OLYMPIC IDEAL The Greek games began in 776 BC as a competition among amateur athletes from the different city - states. The purpose was to bring the citizens of the rival cities together in an apolitical gathering, which would reduce squabbling and develop a larger sense of community.
The rising merchant class in those cities subsequently inverted their purpose by introducing the idea of city rivalry into the games. The city - states then began subsidizing their athletes indirectly and often invisibly. The amateur athletes were soon living a parody of amateurism. They had careers and future income riding on the competition. Winners became heroes, that is to say political heroes. They were fed at the cost of the state for the rest of their lives.
Subtle corruption gradually turned into rank dishonesty. Athletes were eventually bribed to lose. In AD 394 the games were abolished because they had become a parody of the amateur idea, a focus of corruption and a source of political rivalry.
The Olympic Games were re - established in 1896 as a competition among amateur athletes. One of the purposes was to bring citizens of rival countries together in an apolitical gathering. What the Greeks managed to do in 1,170 years, we have done in less than 100.
