Will the real Joe Biden please stand up?

Watch Sen. Chuck Hagel give fellow Sen. Joe Biden a big surprise.

WASHINGTON (CNN) - Members of the Senate Foreign Relations Committee were seeing double on Wednesday morning.

To celebrate Halloween, Sen. Chuck Hagel, R-Nebraska, dressed up as his colleague and friend Sen. Joe Biden, D-Delaware - decked out in a Biden mask and a "Biden for President" t-shirt. As he approached Biden's seat, he raised his arms and said, "Happy Halloween, Biden for President."

"I'll tell you what, Hagel for Vice President," Biden responded with a smile.

Hagel, who has a tradition of wearing costumes to work on Halloween, has previously dressed up as Sen. John McCain, R-Arizona, former Secretary of State Colin Powell and Sen. Pat Roberts, R-Kansas, according to his Senate office.
