You know what's a good idea? Having a desk clock in the shape of a metal revolver. The pistol clock costs $20 and is perfect to keep in your pocket so you can whip it out whenever you need to know the time. Especially around police officers. Don't even wait for them to ask the time, just pull it out and tell them. You'll be doing them a favor. Just make sure to get their attention first by yelling something like, "Hey, cop!" And then yank it out of your pocket quickly. For extra fun you should also probably yell "Bang bang bang!" Because, you know, people really like hearing that right before the time.
