Eric McCormack, the Emmy-winning star of Will & Grace, is making his triumphant return to television as an ad man in TNT's Trust Me. He tells Rachael how he decided to do the project. "It had to be fun; I had eight years of fun with great people," Eric says about his time playing Will Truman the hit show. "I didn't want to be a lawyer or a doctor. I thought somewhere out there, there's got to be a new milieu, and all of a sudden it's advertising. I thought, this is great -- it's cutthroat and it's creative. It's not life and death, but it kind of is for these guys."

If it's cutthroat Eric likes, then Rachael's got the perfect challenge for him! When his former co-star Debra Messing last visited Rachael, the clock was ticking as she matched Hollywood starlets with their ex-husbands in a game called "The Ex-Factor." Can Eric beat her time when he tries to pair famous TV characters with their on-screen bosses? Watch the video above for a game of "Who's the Boss?"
