2. Sandwich
In May 2013, a student at Marsden High School in Queensland was suspended for throwing his ham sandwich at then Prime Minister Julia Gillard. The prime minister, who was busy greeting other student, didn't seem to notice the piece of sandwich flying at her. But unfortunately, the boy's teachers did.
3. Shoe
While on ABC's 'Q&A' program, an audience member threw both of his shoes at former Prime Minister John Howard. Eventually the host, Tony Jones, stood up and asked security to escort the man out. The audience however continued to sling insults at the former PM telling him to "get out" and screaming "you've got blood on your hands". Howard simply laughed it off.
4. Pie
Former French president Nicolas Sarkozy came face to face with a creme pie early in 1997, when he was mayor of Parisian suburb Neuilly-sue-Seine. The culprit was a noted Belgian pie-thrower of the name Noel Godin.
5. An Egg
While campaigning for the governorship of California in 2003, Arnold Schwarzeneggar was hit by a raw egg. Fortunately it only stained his blazer, which he cooly removed as he continued greeting his fans and supporters. The best part, however, was the future Governator's reponse to the incident - the guy now owed him some bacon.

8. A Cloud of Purple Powder
Whilst debating in parliament in 2004, then UK Prime Minister Tony Blair was ambushed by a cloud of purple haze from the public gallery. The powdered descended suddenly upon the PM, causing the Speaker of the House to suspend proceedings.
The pressure group Fathers 4 Justice, which campaigns for better access for divorced fathers to their children, claimed responsibility for the action.
