Do something nice for someone, evebody wins

Because I tend to watch a lot of sports on television, I see a great many commercials. Now, like many of you, I often get up to grab a snack or, um, visit the little room down the hall during those breaks in the action. Sometimes, though, I just sit there watching and waiting for the game to come back on.
Hey, I'm a guy. I'm not that complicated. If the game's on, I'm not hungry or I don't need to, you know, visit the little room down the hall, I'll just sit there with a stupid look on my face, thinking about, well, nothing in particular.
The other day I was cemented to my easy chair and saw a commercial for an insurance company (what are the chances, right?) . I'm guessing you've seen it, too. It's not the one with that goofy chick, Flo, or the one with the talking lizard (I know, I know, it's not a lizard). It was a serious one that shows a woman witnessing someone doing a good deed for her. Then she, in turn, does a good deed for someone else, who does a good deed for someone else ... and so on, and so on.
I think they call that "paying it forward."
