One of the great things about YouTube is that every gaffe made by politicians will be preserved for posterity, as an endless source of amusement for future generations. Tony Abbott's "suppository of all knowledge" is hard to beat, especially from a Rhodes Scholar, but my own personal favourite is Julia Gillard's mispronunciation of the word "hyperbole". I now use it myself at every opportunity, and given that she's a big footy fan in my home town of Melbourne, I'd like to see the AFL Grand Final renamed the Hyper Bowl, as an enduring tribute to our first female PM. This would be in keeping with the Australian practice of commemorating Prime Ministerial stuff ups, like the Harold Holt Memorial Swimming Centre, named after PM Harold Holt who drowned while in office in 1967.
