BBC Mistakes a Cab Driver for an Internet

This is one of the funniest videos that is painful to watch. For a segment about online audo downloading, a BBC interviewer thinks she's speaking with the editor of a technology website- New and Wireless. What she doesn't realize is her interviewee is a cab driver that was booked for another segment. What makes this video so delightful is: a) The cab driver's face when he's introduced, b) That the cab driver decides to wing it and offers some commentary on the subject, and c) That when the mistake is realized, they switch to the real expert without acknowledging the blunder.
