 After a while, Sarah switched technique and finally managed to wrestle up a crowd through the simple tactic of making a series of insanely terrible guesses. First, there is a dad who looks like he's 42 and in fact is 42. Sarah guessed as 25. Then a grandmother who was standing there with kids and grandkids. Sarah writes her guess for this woman's age on a whiteboard. This could be really wrong. I get the feeling it's really wrong, but that's okay. We'll see.
