I wish I were a celebrity.

To get ratings, reality TV shows are inviting celebs to drop in. And they get to do cool stuff.

I’d sure like to banter with Jane Lynch on “Celebrity Game Night” (10 p.m. Tuesdays on NBC). Hey Jane, I’m great at Pictionary. I can even draw with my eyes closed!

I could use a lesson on dancing while suspended from a wire — one of many neat skills taught to luminaries like Joe Jonas on NBC’s “I Can Do That,” which was just renewed for a second season.

Best of all, celebrities, who clearly have lots of money, can get a free family tree! “Who Do You Think You Are,” the TLC show that traces the roots of famous folk, began a new cycle Sunday (9 p.m.). Sweet-faced Ginnifer Goodwin (“Big Love” and “Once Upon A Time”) found out her mysterious great-grandfather was a bootlegger who served time.

(As an aside, let me say: Kudos to you, Ms. Goodwin, for being open about everything, unlike supercelebrity Ben Affleck, who told PBS’s “Finding Your Roots” series not to mention his slave-holding forefathers. PBS withheld the info, leading to a scandal that put the show on hiatus for a review of its practices.)

The Affleck flap is a reminder that being a celebrity on TV isn’t all peaches and creme de cassis.

And some celebrity TV shows do sound pretty awful. In a few weeks, England will launch “Celebrity Big Brother.” Rumored residents of the Big Brother house include acid-tongued comic Kathy Griffin, slightly nutty supermodel Janice Dickinson and wrestling star Hulk Hogan, who got in trouble recently for making racist remarks.

I’m happy to watch such a train wreck — and glad not to be in the house.
