- How many feet are in a meter?
- What species of fish is Nemo from Finding Nemo ?
- Who wrote The Adventures of Huckleberry Finn ?

I believe my approach stands out because my content could be used in high schools and colleges. I prioritize questions that are educational and thought-provoking. For example, if I hear an interesting lyric in a rock and roll song, I'll develop a question from it. A new one I haven't used yet is, "What is the name of the song that repeats the lyrics 'a little bit softer now' 17 times and 'a little bit louder now' 12 times?" The answer is "Shout" by the Isley Brothers.
Sometimes, I create unique questions you won't find anywhere else. For instance, I once looked up how many number-one songs the Beatles had on the Billboard chart—it's 20. I use these types of questions to break ties at the end of my events.
