So first they came for the cows
then they came for the lambs.
Then they discovered there was actually a beneficial reason all that belching went into the atmosphere (other than to cover up Uncle Walt's after dinner bouts with flatulence). Only it's too late and with no belching going on, mankind bids farewell to planet Earth and the last man digs his own grave and lies down in it to join the cows and the lambs. Oh, and the lions inherit the earth. Being on a strictly meat diet, they never belch.
