In this joke on the Chick-fil-A "Eat Mor Chikin" ads, chickens make a presentation to people entering a chicken restaurant showing how cow flatulence is causing climate change due to the release of large quantities of methane. Then in the next scene we see global warming activists chasing down a herd of cattle, and after a cut, we see them all barbecuing steaks and ribs on the cattle ranch, to the surprise of the ranch hands. Then the announcer says: "Actually it's cows that are causing more environmental damage than chickens, so eat more beef, at the place for beef: Arby's!"
Then, in the next ad, we see a bunch of vegans being indoctrinated by climate activist chickens, and so enlightened as to who is really responsible for more impact on the climate, all the vegans decide to make an exception to their diet to eat beef to punish cows for global warming. And then we're told where to go to help fight climate change: Arby's, the environmental fast food restaurant chain for beef eaters!
