Corinna Draschl
Reigning Junior World Memory Champion Corinna Draschl came all the way from Austria in 2007 to take Oprah's memory challenge. Given the photos and names of 50 random audience members, the 17-year-old only had 20 minutes to learn them all. Adding to the pressure, Corinna wasn't familiar with American names.

"I memorize it, go through it, repeat," she said. "Sometimes I take something really special for the person, like your hair. If she has braids or something, and link it with the name."

When put to the test, Corinna aced every question!
