Saw that on the news the other night. It reminded me of "Lancelot the Living Unicorn".
Lancelot appeared at MNRF in the early 1980's and was a goat whose horn buds were surgically moved to the center of it forehead when it was very young resulting in the grow of a single horn. In 1984 the U.S. patent office granted patent number 4,429,685 to Timothy G. Zell for his development of a surgical procedure to create a "unicorn" from a horned animal. The basis for the patent was "Lancelot the living unicorn" bred by Timothy "Otter" Zell and his wife Morning Glory Zell.
