Generic Great Opening for Message Introduction...

John Ortberg had this great generic opening for his message "The World's Greatest Wisdom: Guard You Mouth" on 07/31/2005 which could be adopted to other situation without much work:

One of the biggest milestones in our society is the sixteen birthday because when you turn sixteen you can drive a car. We don’t let just anybody drive a car. You have to go to the DMV and take a test and get a license because a car is a life or death deal. So we make people go through some hoops before they can get a license if they are going to drive a car.

Having a gun is a pretty serious deal. We had dinner recently with a guy from this church, who had been hunting and been successful, and he wanted to celebrate that he had taken his gun and shot little defenseless bunnies and little deer like Bambi. So he invited us over for dinner, and we did that. Before you get a gun, you have to have a license because a gun is a life or death deal.

I was thinking this week that there is a force that is more powerful than cars or than guns because it means life or death not just to the body but to the soul, and every human being is issued one. It’s called the mouth...

How's that for a great opening template?
