A physicist, a biologist and a statistician go hunting
They are hiding together in the bushes and they see a deer 70ft ahead of them.
The physicist makes some calculations, aims and fires at the deer. His shot ends up 5ft to the left of the deer.
The biologist analyzes the deer's movement, aims and fires. His shot ends up 5ft to the right of the deer.
The statistician drops his rifle and happily shouts, "WE GOT IT!!"
