You've seen them on TV, those commercials where real people share the story of the moment the light bulb just came on. Now Mutual of Omaha wants to hear yours.

The insurance company will be in Lexington from 11 a.m. to 7 p.m. Thursday and Friday at Cheapside Park, at West Short Street and Market Street, taping "aha moments." Look for the 34-foot silver Airstream trailer, which is on a 25-city tour looking for candidates for next year's ad campaign.

According to the company's Web site, an "aha moment" is "a moment of clarity, ... a defining moment where you gain real wisdom — wisdom you can use to change your life."

If you can't make it downtown, you can post your moment online, and watch others for inspiration, at www.ahamoment.com.
