Who's the better gift giver: Barack or Michelle?

The first lady says she is.

On Christmas at the White House: An Oprah Primetime Special (airing Sunday on ABC), Winfrey asks Barack if he feels more pressure to give good gifts now that he's the president -- or if he can get away with giving a less desirable gift.

His answer ignites a cute debate with the first lady.

"I have given some good gifts - you get some nice stuff - here's the general rule, I give nicer stuff than I get," Barack begins.

Michelle quickly interrupts, "No way! I gave you good gifts last year!"

"Absolutely - aw, come on, please," he replies. "You know, it's like Mother's Day and Father's Day."

Michelle quips, "We're talking about Christmas, don't become distracted..."

The two - who will celebrate their first Christmas in the White House this year - also reveal the best presents they got as kids.

Michelle says her top gift was "a metal doll house with plastic furniture ... I remember I really didn't know how to set up a house, so I had all the furniture lined up along the walls, as opposed to nestled around the fireplace, but I loved that little doll house."

Barack's top present?

"A bike one year," he tells Winfrey. "Getting that first, big kid 10-speed bike that's always ... special."

One year, Barack - whose parents separated when he was 2-years old and later divorced - also says his father visited him from his native Kenya and gave him a basketball.

"It wasn't until much later in life that I realized, 'Actually, he gave me that basketball,'" he says. "I think there was some cause and effect there in terms of the degree to which I just ended up taking up the sport as a kid who didn't know his dad."
