How do I build a ________?
How does _______ work?
Why doesn't ______ ?
Can you explain that stuff about _____ again?
How long before I can build a death ray?
Why do you know all this?
Why didn't you talk more about ponies?
Did you know people are 1 076 189 times more likely to die in a car accident than from a shark attack, yet there are no horror movies about pedestrian crossings?
