Few employment opportunities are a lock in these uncertain times. But my unscientific survey indicates that if you’ve appeared on one reality show, you have a better-than-average chance of starring on another. Perhaps several. And if you are descended from a reality star (or a real star), your chances of another gig are all but certain. I call this Carnie Wilson Syndrome. But it could just as easily be labeled the Nicole Richie Effect.

As evidence, I offer “Haunted Highway” (9 p.m., Syfy), starring Jack Osbourne. In the “Addams Family” world of MTV’s “Osbournes” reality series, brother Jack was typecast as Pugsley to sister Kelly’s Wednesday. All four Osbournes have gone on to a multitude of cameos and starring gigs, most notably, their mom Sharon, who is a regular fixture on “America’s Got Talent.” Kelly has been on “Dancing With the Stars” and too many other shows to mention.

On “Highway,” Osbourne joins Jael de Pardo, Dana Workman and Devin Marble as they investigate paranormal tales in odd corners of these United States. First up, a trip to Bear Lake, Utah, to look for the elusive Bear Lake Beast, said to be a 20-foot-long reptilian monster. Reported by multitudes, it’s never been caught on camera. Funny how that happens when you’re “elusive.”

In the weeks since “Highway” was produced and promoted, Osbourne has announced that he is suffering from numerous health ailments arising from multiple sclerosis.

• Another example of second-generation reality stardom, “Bristol Palin: Life’s a Tripp” (9 p.m., Lifetime) documents how the famous daughter of the former Alaska governor raises her bundle of joy while living in a Beverly Hills mansion roughly the size of an Olive Garden restaurant that’s on loan from a family friend. Just how many people from Wasilla live in Beverly Hills?

Tonight’s episode takes Bristol, her sister Willow and their famous mother on a trip to our nation’s capital to appear at last February’s Conservative Political Action Conference.
