This is from last year's G8 summit, but I thought it was pretty funny. The idea of any man who can't ride a bicycle makes me laugh, and the fact that it was Bush, well, that makes it funnier:
http://news.independent.co.uk/uk/this_britain/article348032.eceThe police report describes him as a "falling object" who lost control of his bicycle after trying to pedal and wave at the same time. [...] Mr Bush was cycling in the grounds when he waved and shouted to a group of Strathclyde police officers: "Thanks, you guys, for coming." This triggered a serious case of wobbles and he ended up injuring a constable. [...] The cause was officially recorded as: "Hit by moving/falling object."
