Hmm, which side is more believable...
Some guy happened to be walking around with a camera and saw a goat stuck in the water, and decided to watch instead of doing anything so a pig comes and saves it.
or...
Some guy pulled a publicity stunt, documented all of it, threatened people with a death penalty on national television, then releases to the public that it was all fake and that no one should find out. Thus, gaining nothing in the end, except a few laughs for his TV show.
Both sound pretty sketch to me so here's my theory.
The first one is fake, and the second is a lie.
