- No balls (Well i guess, technically, he has a couple, :D)
Was he an olympian?
- yes
- Is he a swimmer?
- If yes, is it Michael Phelps?
If not a swimmer, is he a track and field athlete?
- yes
- yes very good, told you it was easy.
OK, part 2, since this went so quickly, answers to question 1-11 are still the same but suppose I answer:
#12. No
#13 Track/Field yes
It is still someone that you should know.
- Is he black?
Is he a sprinter?
- Yes, he is black
- yes, he is a sprinter
- Did he compete for Team USA?
Having successfully guessed Phelps, I’ll start another 20-questions game after this one runs its course.
- Is he Usain Bolt?
- Yes, it is bolt…
Go ahead EH, give us your best shot!!
OK. I’m thinking of a name.
Er… does that mean, like, a person?
- Yes.
- Male?
- Western Hemispherean?
- Alive?
RNATB we established that Western Hemisspherian was not a good question as it could include parts of europe and Africa.
Can i replace it with
- “From the new world?”
I know. I was the one who established that. 
I worded it that way deliberately, though.
- Yes
- Yes (and also “from the New World”)
- No
aka “America” or “the Americas”
