Cow: "Hmmm-hmm-hmmm ... (he Looks Up And Reads The Sign) 'I Know I Am A (coe).' ... That Doesn't Sound Right."

(A Farmer Comes In, Grumbling)

Farmer: "Mumble-mumble -- You're Not A Coe, You're A Cow!"

Cow: (brightly) "I Get It! Hmmm-hmm-hmm -- 'I (now) I Am A Cow!'"

Farmer: (walking Around, The Cow Looks Confused) "Grumble-grumble-grumble ... Listen -- 'I KNOW I AM A COW.'"

Cow: (smug) "You're Not A Cow!"
