TV titan Regis Philbin has a place in the Guinness Book of World Records for spending more than 17,000 hours in front of a TV camera.

He said, "It's important to find that chemistry as soon as you can, to stick with it. You know, I find that if you continue the relationship beyond the desk, sometimes that could be an effect -- have a bad effect on your on camera relationship."

Philbin also discussed his memoir, "How I Got This Way," his wife, Joy, and why he decided to leave television, and if he'll have a part in choosing his successor on his former show. For all of that discussion and more, check out the video in the player above.
