At the risk of sounding horribly pedantic, cow farts aren’t the problem. Though it’s not nearly as funny, belches are the main source of methane from Ol’ Bessie. The way they digest food, most methane is produced early on in their stomachs, not later on in their intestinal tracts. And their total contribution (no matter which end it comes out of) is about 3-4% of AGW.
Technically, not grandparents: grandmothers. Old fart males like me are evolutionarily useless. Just like my wife the grandmother tells me all the time.
After watching the way the Eagles & refs beat the Dolphins, I’d say the SB fix is already completed!
