Here’s one shared by Tim Johnson of China Rises:
“At the closing ceremonies, International Olympic Committee President Jacques Rogge announces that the IOC has decided that the next Olympics will be held again in Beijing instead of London since the games were so successful. The news sends millions of Chinese into a faint. Even the doctors swoon. Only the police are strong enough to withstand the news, and they immediately shout in unison: “Go to hell, Rogge!”
The other joke is on “You and me” the song sung by Sarah Brightman and Liu Huan at the Olympic opening ceremony which is now said to be a song about rising oil and food prices, since “you” in Chinese is a homonym for oil (油) while “mi” sounds like rice (米).
