Astronaut: Come in Houston, We've landed on the moon. I repeat, we've landed on the moon.
Houston: Good for you. How was your landing?
Ast: Not good. One of our legs sunk in to the ground. Could it be quicksand? Houston? is there quicksand on the moon?
Hous: How should we know? We've never been there, you tell us.
Ast: Hold on, we're going to check. Over and out.
Hous: Dave? are you there? do you copy?
Ast: Uh... Houston, we have a problem.
