Welcome to Springwood Lakes. May I take your order?

During announcements this morning one of my students looked up at the PA and squaked, "Shut up already!"

I had to step in and say, "You do realize that the speaker isn't an intercom, right? We can hear them, but they can't hear us. You see, it's not like working at McDonald's and you can take their order. Speaking of, here's today's test." After handing the test to her, I darted to my overhead and covered it up because I didn't want her start screaming, "Quit it!" into its fan.
