Tennessee Fainting Goats:

Despite the name, these goats do not actually faint, but rather have a genetic problem with their muscles that cause them to fall over whenever startled or surprised.  This does not hurt the goat.  In fact, this action is really a defense system.

Jacobs 4 Horned Sheep:

Jacob’s four horned sheep are different from other sheep in that they have four horns instead of the normal two.  They are a domestic and ancient breed of sheep.  These are the same species of sheep often referred to in the Bible.
