joshbrown: Did you know that they tried using gerbils in airport security? Because they can smell fear, so what they did was they took a fan . . .
My father: But it must work only at a very short range. Surely a more effective way to do it would be to have the passengers take off their clothes and climb into a box of gerbils . . .
Me: And if they say, "Do it to Julia!" they can go on the flight.
