Edit: Thanks to NastyMastaDaddy for finding the episode! Episode 31, question 7, answer Y.
The question was one of those "put these things in order of first appearance" and the options were: World Wildlife Fund, Walt Disney World, World Wide Web, and World of Warcraft. That's the correct order, by the way (WWF, WDW, WWW, WOW).
I got it right and it popped. I guess it has to do with it being a "World of Warcraft" question. There may be others? If anyone can confirm the episode number this occurs in before I get back to finding it out myself, let me know in the comments and I'll update this.
