B: "10 (this is one of the two typical answers to this question in our household), and how much out of 10 do you want to ring and have a playdate?"
C: "Googolplex" (this is in the vein of the other typical answer in our household)
B: "Coco, do you realize that even most adults don't know what a googolplex is?"
B: (to a middle age couple walking by) "Excuse me, do you know what a googolplex is?"
Strangers: "No--what is it?"
B: "It's a very large number"
Strangers: (with look which seems to communicate "You are one wierd cookie") "Ok, thank you for that."
B: "Coco, did you know that there's a number even bigger than googolplex?"
C: "No, you said that was the biggest number."
B: "Oh, did I? Well I learned a bigger one. It's called G64"
C: "Oh, OK, I want G64 out of 10 to ring and have a playdate"
