Rush Limbaugh isn't very happy about CBS' announcement that Stephen Colbert is replacing David Letterman. Not happy at all.

After moaning that "ColBERT" has declared war on the heartland, he went on to say "no longer will comedy be a covert assault on American values. Now it's just wide out in the open."

Rush somehow thinks it will also mean comedy and humor will be redefined. This, from the man whose vile statements are often defined as "comedy."

I can hardly wait to see what BillO has to say about it after his deranged rant earlier this week.
