If any of my last three reasons to smile were successful, you probably experienced a sort of satisfied smile. If you prefer the laugh-out-loud variety, I found one last night.

Have you seen those television ads for a home security company that tries to make single women afraid to live alone? Saturday Night Live has aired a great spoof of them.

"Are you a single woman who lives alone in a large five-person house?" the spoof asks. If so, it continues, studies show that "most men want to kill you." You can watch the whole thing here (after the obligatory opening promo).

Have your own reason to laugh or smile? Please share it in the comments section.
