We've Been Duped

It's a commonly held notion that cows aren't the sharpest tacks on the board. They certainly don't understand English, right?

My theory: cows just want us to believe that so we're not expecting them to obey us. 

Case in point: when I say, "Time to go to new pasture, ladies," they all get up from their naps, moo loudly, and follow me at a trot. But if I walked out into said new pasture and said, "Time to go to back to the old pasture," everyone would play the deaf-and-dumb-cow card.

"Saying to those who are bound, 'Go forth,' ... They will not hunger or thirst ... For He who has compassion on them will lead them and guide them to springs of water." --Isaiah 49:9-10 (NASB)
