Kevin Rudd and Julia Gillard when they were in Government
Good question: looked it up. A variation originated during WWII with marines fighting the Japanese in the Pacific. "The garbage hit the fan", "the Shinto hit the fan". There is also an old joke about a man in a crowded bar who couldn't find the restroom. He went upstairs and found a hole in the floor where he relieved himself. When he went downstairs the bar was empty except for the bartender. There was crap everywhere. The man asked the bartender what happened? The bartender replied "Where were you when the **** hit the fan?"
Someone must have tried it once ! :)<br />
When they rented an apartment with a hole below in it.<br />
This came from the ones who lived below and they realized it.
