Mystery scars on Obama's head prompt another question from conspiracy theorists - has the President had brain surgery?
He has been plagued with questions and doubts concerning his background throughout his first term as President.
Questions like - is Barack Obama actually American? Is he a Muslim? Is he actually an alien from another planet? - have frequently been asked.
The next question circulating on the internet - has President Obama had brain surgery?
Internet blog sites, conspiracy theorists and forums are awash with rumours as to what those mystery scars on the president's head are from.
In pictures, Obama appears to have a long scar which goes up the side of his head and over his crown.
Some conspiracy theorists claim they are scars that you would see on someone who has had brain surgery.
But without medical records (along with his school records and birth certificate) no one seems to be able to provide an answer as to the cause of the mystery scars.
