Question Is there a cure for the bubble? You think we're gonna run out of questions? Do you have the cure with you? Does someone you know have it? It it your mom? Is the address (Bob's mother lives in) greater than 15? Is it greater than 23? (Is it) 17? So, you think you will beat us, huh? Wait, you counted that as a question? If you're going to trick me into asking another question, you're wrong. Aren't you? Does your mom live in a floor that's greater than 15? So she must live in a floor that's less than 15, right? I understand you have the cure, do you? Whoa, whoa, whoa, your questions count too? Ma'am, is it behind your back? Is the first digit greater than 5? Is it (the first digit) greater than 2? Is it (the first digit) 3? Do the numbers in the code go backwards from 3?
