Stephen Colbert recently spoke at an event for those named to the list of Time Magazine’s 100 Most Influential People and while his razor sharp, “is it a joke or not?” humor roasted much of the crowd, he saved his best lines for union enemy #1, David Koch.

After cracking jokes about Secretary of State Hillary Clinton, Sandra Fluke, Chelsea Handler, Cardinal Timothy Dolan and Louis C.K., Colbert turned the topic to Koch — who was in attendance — and the amount of power he has over American politics. Colbert took some extended shots at Koch compared to the one-liners he used for everyone else:

Of course, all of us should be honored to be listed on the TIME 100 alongside the two men who will be slugging it out in the fall: President Obama, and the man who would defeat him, David Koch.

By the way, if David Koch likes his waiter tonight, he will be your next Congressman.

In the past week, the Koch Brothers political front group, Americans for Prosperity, launched a $6.5 million campaign of anti-Obama television commercials in Colorado, Florida, Iowa, Michigan, Nevada, New Mexico, Ohio and Virginia that suggests money from Obama’s $814 billion economic stimulus package went to overseas green-energy companies. The Koch Brothers’ fortunes are going toward misinforming America about key issues, so it may take a man with an audience as big as Stephen Colbert to get the public to understand the danger of their string-pulling ways.
