Well, that's the watered-down version.
Russ really went to Africa on a man-hunt to find more goats. There, he got delusional and thought that one of the goats was his sweetheart, in real life (on DS, she is known as Starfish Scientist). Some say that he was hypnotized because he got down on his knees and prepared his proposal and bared his love to this goat! (I hope that it was a female goat). After the goat had grunted, Russ was estactic that his sweetheart had said YES! When he tried to place the ring on its finger, that was when he realized that he picked up the wrong size. Well, the rest is pretty much history.
