Omarosa and Trishelle's amazing race

Fifteen minutes of fame? That's so 15 minutes ago, people. Today's reality-show ''stars'' know that with plenty of shameless self-promotion and a liberal slathering of elbow grease, they can score 15 minutes from every station on the dial.

Why, just today, Bravo announced its lineup for the upcoming season of Celebrity Poker Showdown, and the August 18 edition will mark what only feels like the gajillionth TV appearances by reality stalwarts Omarosa Manigault-Stallworth (The Apprentice) and Trishelle Cannatella (Real World: Las Vegas). Amazingly, both women will also pop up on Bravo the previous evening as commentators on Battle of the Network Reality Stars. Gah!

So exactly how many non-talk-show TV, film, and video credits have Omarosa, Trishelle, and fellow fame-o-sexuals Trista Sutter (The Bachelor), Colby Donaldson (Survivor: The Australian Outback), and William Hung (American Idol) managed to rack up? We logged onto IMDB and using our shaky math skills and highly unscientific criteria for weeding out projects viewed by less than four people, tried to determine which of the quintet is most in-demand (or has the hardest-working agent).

Trishelle: Lingerie Bowl, The Hillz, Kill Reality, William Hung: Hangin' with Hung, Spring Break Celebrity Fantasies, Real World/Road Rules Challenge: The Inferno, The Surreal Life, Real World/Road Rules Challenge: The Gauntlet, Celebrity Poker Showdown, The New Tom Green Show, Punk'd Total: 11

Trista: Dancing with the Stars, Trista and Ryan's Honeymoon Hotspots, Trista & Ryan's Wedding, The Bachelorette, The Bachelor, Fear Factor, Less Than Perfect, According to Jim Total: 8

William Hung: My Crazy Mother, William Hung: Hangin' with Hung, George Lopez, American Idol Total: 4

Well, huzzah to Colby for not only the longest list of credits, but the least embarrassing, too. (He was actually pretty funny on Curb Your Enthusiasm). As for Trishelle's participation in William Hung: Hangin' With Hung, I invite all PopWatch readers to join me in a massive ''hell to the no!''
