Think about these questions?

At lunch the other day a friend of mine showed me a list of interesting questions. I felt like sharing a couple.Enjoy!How does the guy who drives the snowplow get to work?If the 7-11 is open 24 hours a day, 365 days a year, why does it have locks on the door?You know that indestructible black box that is used on airplanes? Why don't they make the whole plane out of it?Why are they called apartments when they are all stuck together?Why does the sun lighten our hair, but darken our skin?Why is it that rain drops but snow falls?Why is it that when you're driving and looking for an address, you turn down the volume on the radio?Why is lemon juice made with artificial flavor and dishwashing liquid is made with real lemons?Why is the time of day with the slowest traffic called rush hour?Why do they sterilize the needle for lethal injections?
