Have witnessed two, one, a buddy of mine we had to talk in to staying through a frost delay, he was ready to leave and not wait for the delayed start. Aced #17.
Another was a in a regular threesome of older guys, I was a single that joined them. Similar to the other story, they hit in the same order on every tee no matter the score. First guy hit it to within about 6 feet, was really pleased. Third guy hit it on line, bounced twice and from what I could tell hit the flag, but green was slightly tilted so I couldn't see the hole. I told him I thought it went in, they thought it went over the green (remember, older guys). Sure enough walking up to the green I only saw the 6 footer. The guy lost the hole with a birdie.
I've had 2, but that's not the point of the story.
