What will aliens think of Keith Olbermann?

I like the newest reason to reduce emissions of greenhouse gases - aliens may think we're a threat with the changes and attack.
But radio signals have been going out into space for over 90 years, and TV signals since the 1930s.
Aliens have had plenty of chances to hear about humanity and it's potential. But when they get a load of Keith Olbermann and his guests, what will they think?
We may be doomed. And Olbermann might have found the way to increase his audience.
