No one will be surprised to find out that Michael Phelps, the most decorated Olympian of all time, was a talented swimmer as a kid. Back in 1995, 10-year-old Phelps recorded the year's fastest 100-meter butterfly time for his age class in the U.S.
What may be more surprising is that in the same year, 10-year-old Kris Humphries clocked the fastest times in six different events: 50-meter freestyle, 100-meter freestyle, 50-meter butterfly, 50-meter backstroke, 50-meter breaststroke and 200-meter individual medley (the last of which is an event that Phelps has won at the past four Olympics).
