So, two cows were walking away from their buddies in the herd down in the vale. They did not want to be seen or heard by the herd’s owner, Farmer Brown.
After they had strolled about a mile away, the first cow asked, “Do you think the boss heard us leave?
“With all the burping by the other ladies, the boss couldn’t hear a tractor with a busted muffler go by him,” the second cow said.
The US Environmental Protection Agency said burps from large ruminant animals, such as cows, pigs and sheep, were the largest source of methane emissions in 2012, beating out the natural gas industry. Contrary to popular opinion, these animals emit methane from their mouths, not their anuses.
