The Apprentice winner and bachelor Bill Rancic has some examples of how a woman can tell when a guy really is into her.

"It's a good sign when a guy is willing to kiss you in public and show affection to you in public," Bill says. "Or, he'll take you to high profile places. If he's taking you to the busiest steak house, you know, in the city, that's a pretty good sign."

Bill says the oldest excuse in the book is: "I'm too busy."

"Let me tell you, Oprah, no one is busier than I am," Bill says. "I go between Chicago and New York each week. And when I'm really into a girl, I'm willing to put 'The Donald' on hold to take her call."

Bill Rancic's new book is called You're Hired.
