“What if I go to a automobile dealership, and I notify my youngsters to select up the car,” and “I say, ‘ah, well mine is the automobile with 4 wheels,'” Moore reported. “Just about every car has a popular framework, it has four wheels – I have not served my young children identify which vehicle to drive off the lot.”
