Sen. Mark Begich's (D-Alaska) 6-year-old son, Jacob, captured President-elect Obama's attention this week the old-fashioned way -- by yelling out his name.

As Obama walked through the Capitol on Monday, Jacob Begich called out.

"Obama!!!" yelled Begich, who was in his father's arms.

"How you doing?" Obama replied, before walking toward the Begiches.

"Good! How are you!?" Jacob Begich responded.

"What's going on man?" said Obama, who then shook both Begiches hands and took a photo with them.
