Newsreaders on TV are encouraged to appear all friendly-like. They engage in a bit of witty banter here and there just to keep the flow of the show running smoothly, especially if it's a morning edition. But it's a fine line between being happy colleagues and, well, deeply inappropriate.
Ouch! I actually went looking for the 'Full Frontal' sketch show's National Nightly Network News clips on YouTube to try and find something to compare with the level of sledgehammer to the face nastiness of that and was left wanting.
C'est la vie. I found this instead.
In other news it only took pages of search results on YouTube for "slip of the tongue, news" to turn up a 9/11 conspiracy video. I am disappoint, world.
