Of course it's the pressure. It's the same thing that happens when some foreign twat comes to a small town in America and asks them a simple question while pushing a camera in their face in order to make the argument that Americans are stupid. Even though the same thing can happen to anybody with a little bit of camera shyness.
Sure the pressure is a factor, but these people are still as dumb as dirt. FROG does not have 3 letters. I dont know if any amount of pressure would make me believe otherwise
