"This is a big f------ deal," Biden told President Barack Obama after introducing him at Tuesday's ceremony at the White House.

The episode quickly got buzz on the Internet.
Biden has a reputation of verbal slips, and he knows it.
The White House response to this one? Embrace it.
"And yes Mr. Vice President, you're right," White House press secretary Robert Gibbs said in a post, or "tweet," on Twitter, the social networking site.
