I had a friend born and living in Iceland that would come and visit Serbia every now and then.
It was a summer day,we were chilling outside,and we heard a low flying plane in the distance.
We all knew what that meant - they're spraying mosquitoes. (As in spraying against mosquitoes)
When we told him that ,he ran inside.
He thought they are releasing the actual insects from the plane.
Y'all crazy atlantic island people
