First time golfing in 4 years...

I hadn't golfed in 4 years because of hip and knee surgeries. Finally went out to shoot 9 holes with my son and on the last tee, I drilled a 4 iron 165 yards directly into the cup! Of course I searched around looking for the ball and never expected to find it in the hole. I was about to drop and take a penalty when my son pulled the flag and noticed ball inside. I did hit it well, but the odds of nailing it into the cup are ridiculous. Plenty of luck went into that shot!
