that wouldn't work...
bulls respond to movement not color
you could put a man in the ring and have him stay in one spot, and then have two cowboys.. run around the man (they did that on the show mythbusters) and the bull would chase the two cowboys.
so
better way is
225: Put him on a moving wire line in the center of a bullring with 12 angry bulls
234. Have my younger sister eat him. (I'm serious... My sister eats paper. She once literally ate half of a letter when she claimed she was so hungry and there wasn't any food around.)
