What it takes to 'Courage!' ?

Cowardly Lion: Courage! What makes a king out of a slave? Courage! What makes the flag on the mast to wave? Courage! What makes the elephant charge his tusk in the misty mist, or the dusky dusk? What makes the muskrat guard his musk? Courage! What makes the sphinx the seventh wonder? Courage! What makes the dawn come up like thunder? Courage! What makes the Hottentot so hot? What puts the "ape" in apricot? What have they got that I ain't got?
Dorothy, Scarecrow, Tin Woodsman: Courage!
Cowardly Lion: You can say that again! Hunh!
