Various security measures are used to protect the US President when he travels: a rocket-grenade launching limo, hundreds of Secret Service staff - and perhaps even a body double.
When Barack Obama rolled into town for the G20 summit in Australia, it seems his lookalike wasn't far away.
As the President was driven through the streets of Brisbane in his heavily guarded limousine dubbed The Beast, a "decoy" Barack Obama was snapped by a local newspaper photographer - apparently in a decoy Beast.
The unnamed possible Obama lookalike even did the obligatory wave for the cheering crowd, the Courier-Mail reported.
If this is a presidential decoy, it's not the first time a world leader has had a body double.
Former dictator Saddam Hussein apparently had multiple lookalikes during his time as head of Iraq and it has been claimed Nazi leader Adolf Hitler had up to six.
