Most golfers spend their lives dreaming of sinking a hole-in-hole - and they might want to stop reading now.
That's because Sheffielder Jack Crisp has achieved the elusive feat not once but twice, at the tender age of 21.
His first came a day short of his 16th birthday in June 2013 on the par three, 145-yard 13th hole at Hillsborough Golf Club.

The golfing gods smiled on him again this summer, once more at his home club, where he has been a member since the age of seven, but this time on the harder 186-yard 10th hole.
One crucial difference was that on this occasion Jack was old enough to buy the drinks at the clubhouse - unlike before, when his dad Richard had to foot the bill.
"I was amazed when I got the first one and I never expected to do it again, especially not so soon," he said.

Jack, who works for Rotherham United Community Sports Trust, visiting schools to run coaching sessions, was playing off a 21 handicap when he hit his first hole-in-one but that is now down to 10.
And while his first had been a rare highlight in what was a scrappy round by his high standards, this was achieved in tournament play and helped him card an impressive seven-over-par score of 78.
As well as the admiration - and envy - of his fellow golfers, the stroke of genius earned him an exclusive Hugo Boss watch awarded only to members of the hole-in-one club.

Asked whether he thinks he can achieve the hat-trick, Jack modestly claimed that would take a large slice of fortune.
"The pros will play for the pins, attempting to win the expensive cars on offer for holes-in-one, but for amateurs it's usually more about luck," he said.
Jack's proud dad Richard, who is a former captain of the club, told how he had watched in amazement as the ball kicked off the bank before rolling onto the green and disappearing down the hole on June 23.
"I couldn't believe it. To do it once is an achievement, but to do it twice is amazing," he said.
"There can't be many amateur golfers of any age who've done that."
Jack, who attends the Peter Cowen Golf Academy in Rotherham, has won a handful of junior competitions as well as a senior club trophy, and his dad said his game is improving all the time.
