Par 4 Hole in One

I was playing with two friends and we approached the 7th hole. This hole is a slight dogleg right and if you cut the corner it is much shorter. I took out my driver and hit it over the right corner at the green. When we approached the green my ball was not on the green. The 3 of us were searching over the green and in the water. One friend decided to play his next shot while we looked and when he went to mark his ball, voila! There was my ball in the hole!
