We expect Jon Stewart and Stephen Colbert to have incisive, funny takes on important green issues like fracking. But David Letterman? That guy hasn’t been cool since like 1991! [Ed. note: I used to watch Letterman in like 1991.] And yet, only like a year after the rest of America caught on about fracking, here’s Letterman railing against “greedy oil and gas companies” on last night’s show.

It’s not strictly funny, but we don’t strictly expect that, do we? And we certainly can’t argue with his final conclusion: “We’re screwed.” Now enjoy musical guest Justin Bieber!
