This whole incident reminds me of a conversation had (strangely) around a dinner table with some friends. One guy was commenting on funny things his young son has said, and one of them happened to be said in a bathroom (loo, or WC for those outside the US). To set up the situation, he mentioned that some guy had gone into one of the stalls and was, "just blowing the place UP!" (meaning, stinking it up pretty badly).

Had he been telling this story in an airport, who knows if he would have gotten to the punch line...
