In case you're not familiar with the Turnip, it's a whimsical Google search, wherein I type a random phrase and we see what kind of interesting pages "turn-up." As always with this feature, the _floss is not responsible for accuracy. If you know one of the below statements/links to be untrue, by all means, let the world know in the comments below.
Today I typed "the only person ever" into Google, unearthing the following:
The only person ever to receive a nobel prize in both chemistry and physics [was] Marie Curie (1867-1934), who received a Nobel in Physics in 1903 and in Chemistry in 1911.
The only person ever to score 100 points in the NBA [was] Wilt Chamberlain.
Kirk Jones - the only person ever to survive an unprotected trip over Niagara Falls
Two - the number of nominations Barry Fitzgerald received in 1944 for his performance in Going My Way - he was nominated as both Best Actor and Best Supporting Actor, the only person ever to have been nominated twice for the same role. He won Best Supporting Actor, but lost the Best Actor race to castmate Bing Crosby. The Academy subsequently changed its rules to prevent double nominations.
Johnny Cash was the only person ever selected for the Country and Rock Music Hall of Fame, until 1998, when Elvis Presley was inducted into the Country Music Hall of Fame.
Steve Redgrave, Olympic rower famous for being the only person ever to win gold medals in five consecutive Olympics.
