What's Mallard raving about today?
Steven Colbert, The WGA.
I'm pretty sure the fact that The Colbert Report is in reruns just means Stephen Colbert, who is probably a member of the WGA (having been a writer on The Daily Show), is unwilling to cross the picket line.
You see, unlike some comic strips which will remain nameless, The Colbert Report uses multiple writers to maintain some sort of standards. For example, they generally won't discuss Thanksgiving leftovers, and if they do they will be funny about it.
