From a recent SI.com daily newsletter:

Sure hope Dave Ladensack enjoyed his round of golf. According to the odds, he'll have to wait 335,000 years to repeat his feat -- recording two holes-in-one during a single round. Bucking odds mightier than lightning-strike proportions, the 47-year-old Ladensack did it April 27 at the Port Huron (Mich.) Elks Golf Club. "I was in disbelief," said Ladensack, who notched his third and four career aces. "It really doesn't sink in right away." A 5-handicap, Ladensack used a 6-iron on the 161-yard seventh hole and, about 90 minutes later, perfected a 4-iron on the 186-yard 14th hole. Chances of pulling off the feat, while hardly scientific, are 67 million-to-1, according to a representative of Golf Digest. That means Ladensack could play 200 rounds of golf a year and not duplicate his feat for another 335,000 years. "From tee to green, I'm not too bad. But my close game, that's bad," he said after finishing with an above-average 81. "I guess it helps that I didn't have to chip or putt."
