Can't remember which one but I seem to recall that sheep farmers made

Sheep chomp grass low, like a lawnmower, cows wrap their tongues around
longer grass and pull it up in clumps. I don't know why I know this, but
someone taught me the difference a long long time ago, and it's stuck in
a strange mental image in my head.
(goats eat like sheep, iirc)
