File these under "Ick." We've got previews of two stories airing Wednesday night that you won't want to miss.
The first, airing on NBC's Today Show and then later at 9pm on Dateline, is an interview Matt Lauer did with Debra Beasley LaFave, the Florida school teacher who had an affair with a 14-year-old student. "I crossed the line that never should have been crossed," she says now, of the 2004 incident.
The other is a preview of Dateline NetCrime: To Catch a Predator, which airs at 8pm on NBC, where Chris Hansen sets hidden cameras on sex offenders. Conan found it funny enough to spoof during the opening of the Emmy telecast, but the real deal is nothing to chuckle about. It's Cops meets old-style 60 Minutes gotcha segments.
