Not paying attention to the perils of climate change because, well, it's simply not funny enough?
David Letterman and U.S. Sen. Al Franken, D-Minn., have teamed up for a series on climate change on Funny or Die with the goal of tackling the topic humorously. We can't say they always succeed, but they give it a try.
In the second episode, Franken tries to explain the impact of the Koch brothers, describing them as "Siegfried and Roy."
Then, Franken goes on to explain the impact of Charles G. and David H. Koch – the real brothers – and their ability to pour money into a political fight. Koch Industries, with billions in revenue, is the second largest privately held country in the U.S. and operates oil refineries and pipelines.
"My Republican colleagues are afraid of them," Franken tells the long, white-bearded Letterman. "They fund Heritage Foundation and all these climate denying and fake science outlets.
Okay, not so funny.
