I love the guy who makes the PA announcements at O'Hare. "The Department of Homeland Security has raised the terrorist threat level to: [and he pauses for just the right amount of time] Orange [and says it in a way that makes you realize that orange is a weird and sunny name for the second-highest alert level]." And when he tells you to report suspicious activity to the Chicago police, you can tell from how he says Chicago that he's really from Chicago. I can't stand how frequently they repeat these useless announcements, but at least they don't sound like every other airport in the country.
