With last week as Whiz Kids and this week as Guinness World Records I was wondering how many contestants they book, and what happens to those who don't get on the show (or alternately what happens if they run out and have to tap dance.) Since you can't just bring someone else down as the next contestant, I think these weeks would be a good time to bring back Fastest Finger First to determine who gets to play next and to finish the week on time.
