Hate to disappoint you, but that never went out on TV (or was intended to). It was originally filmed for what's called a 'Christmas Tape' which something TV companies make at the staff's xmas parties (and other material such as outakes and deliberate stuff like this as well is included.) See http://en.wikipedia.org/wiki/Christmas_tape for more. [Reply]
It's always such class when shows create a funny never to be broadcast special. And even better that people manage to get hold of them and stick them on youtube [Reply]
