In an appearance on The Ellen DeGeneres Show today to promote his new book, Boom!, NBC's Tom Brokaw told Ellen, "It's great to be here, and my daughters are going to be so relieved. They're such huge fans of yours, and they were terrified that I was going to attempt to dance."

Ellen then, of course, tried to get Brokaw to dance. "Oh, come on!" she said.

"No!" Brokaw replied.

But, as the show went to break, and music started up, Brokaw relented and did a short dance with his host. You can see the clip at the Ellen show site (by clicking on "Mon").
