Had a similar experience with the trusty Acme Tornado on my keychain, although it was inside - a very loud pre- Parent-Teacher Association meeting hubbub, lots of chatter, and the microphone, as usual, wasn't working. The PTA president, a woman who was soft of voice, kept trying to get everyone to quite down and get seated so we could get started. After about 5 minutes of that, I asked if she wanted the room's attention, she said yes, I gave one brief but authorative toot from my Tornado, and we got on with the task at hand. And several people asked to see it after the meeting, so I got to slip in a little preparedness pitch as well!
