He-Hog The Atomic Pig (found uncut animated pilot; 1999)
He-Hog The Atomic Pig was created by John Kricfalusi. A pilot was made in early 1999, but it was rejected. The pilot can be found on the Internet. However, the more commonly circulating version cuts out the psychologist section, where He-Hog consults a distressed woman experiencing puberty. Without that scene, the pilot was shortened from 15 minutes to slightly above 10. That version was circulating since 2013. However, in 2015, the uncut version was posted on YouTube and in higher quality than the other version.
