Comedian Stephen Colbert dropped by the White House this afternoon to tape a segment for his show that included White House spokesman Tony Snow.

Mr. Colbert, who hosts "The Colbert Report," gained national fame and infamy for his 2006 speech mocking President Bush at the White House Correspondent's Dinner.

Mr. Snow was all smiles, however, as Mr. Colbert asked him to sign a cast on his left hand. Mr. Colbert said that House Speaker Nancy Pelosi, California Democrat, had already signed the cast and that he was trying to "heal America" and also "raise wrist awareness" by getting Democrats and Republicans to sign his cast.

The White House press office played along, filling the White House briefing room seats with various bystanders. Press office staffer Peter Seat even went so far as to give a fake "two minutes to the briefing" announcement over the intercom.

Before Mr. Colbert met Mr. Snow, however, CNN's Suzanne Malveaux asked Mr. Colbert what he was doing at the White House. Mr. Colbert's answers were almost intentionally bizarre, as if to provoke awkwardness and embarassment.

Watch Ms. Malveaux's interview of Mr. Colbert in the video below.
