Answer:
Brown I am and much admired. Many horses have I tried. Tire a horse and worry a man, tell me this riddle if you can. What am I?
I have three heads. Cut off one I become stronger. Cut off two I become ten.
Every dawn begins with me. At dusk I'll be the first you see and daybreak couldn't come without. What midday centers all about. Daises grow from me I'm told. And when I come I end all code but in the sun I won't be found. Yet still each day I'll be around.
I am an activity involving pins flying in the air.
My head bobs lazily in the sun. You think I'm cute for my face is yellow my hair is white and my body is green.
I flow from the Homerβs mouth when he sees doughnuts.
