Mel Gibson was born in Australia but his father was an American.
So you guys are to blame.
His ex wife who he had 8 kids with is from Adelaide, South Australia.
Mel is a local legend here. He and his wife used to own a house in Adelaide and was often seen in the local delicatessen buying a Mars bar and Coke.
I never saw him but my sister in law bumped into him once at the local "Foodland" shopping center.
